Capybara Diet. Includes Treatments For Dietary Health Issues. 水豚飲食. カピバラダイエット

The correct diet is very important for the health, welfare and longevity of a capybara.

Includes details of Critical Care Formula for capybaras, Probiotic treatments for capybaras and details of Milk Formula specifically formulated for baby capybaras

The capybara digestive system evolved over 30 million years to take advantage of a diet that was high in fibre and low in calories. If you want your capybara to live a long and healthy life you should try to replicate this diet as closely as possible.

Sugar and Stress are two of the most potentially life-threatening causal factors a pet capybara can encounter. Capybaras should not be given anything with sugar in it like candy, ice cream, sweetened yoghurt, ice lollies etc. Neither should they be given junk food. This seems like common sense but it is surprising how many people, out of ignorance, will feed their pets whatever junk food they are eating. In addition, Exotic Animal Vets warn about the potential harm in feeding the naturally occuring ‘sugar’ in sweet vegetables and fruit, specifically mentioning sweetcorn because of the high sugar content, so you can imagine how disastrous any food with added sugar would be.

A leading breeder of wild animals, Kapi’yva Exotics, posts this information on their website: “I DO NOT recommend feeding fruits, vegetables or other items containing large amounts of sugar on a daily basis. There is some evidence that diets containing large amounts of sugar, even from healthy sources, can cause liver and heart problems.” Kapi’yva Exotics no longer sells capybaras as pets because too many pet capybaras suffer, they only sell to zoos.

Animals do not have the same tolerance for unnatural feed that humans have. This is especially true in the case of a capybara, whose digestive system is exceptionally sensitive, and has been described by at least one expert as the ‘weak link’ in terms of capybara health. I know of several capybaras who died prematurely, in one case after only a few months, because of diet.

The healthiest pet capybaras that I have met are fed a diet of fresh untreated grass, hay (Orchard Hay and Timothy Hay), palm fronds to chew on and guinea pig feed.

Put simply:  DO NOT FEED YOUR CAPYBARA ANYTHING WITH ADDED SUGAR AND ABSOLUTELY NO CANDY or  JUNK FOOD; or  SWEET FRUIT or Bird seed. In the Tropics; capybaras spend 31% of their time grazing during the wet season; and 42% in the dry season.

The olive shaped, green, separated droppings  are a sign of a healthy capybara in the wild.  Softer, sausage shaped faeces may indicate that the capybara is being fed the wrong diet. Fruit, carrots, sweet corn etc may be responsible.

Please also see this blog for information about plants, chemicals and other potentially lethal dangers that capybaras may encounter:

Keep some hay or a bale of hay in the living room so your capybara always has something to eat and chew on. Capybaras have evolved to spend at least 31% of their day chewing (on high fibre, coarse food like grasses) in order to keep their teeth healthy. Hay adds a beautiful aroma to the smell of a living room.

Romeo never chews on furnishings or plastic because he always has hay to eat in the house

HEALTHY TEETH:  To avoid your pet capybara ending up with very painful, life threatening (not to mention expensive) tooth problems, it is essential to include a lot of coarse grazing in a capybara diet.  Unlimited Fresh grass should be a staple part of every capybara diet.  Hay that is of lower nutrition is more suitable for a capybara’s digestive system and means they will eat more, which equates to more fiber and more tooth wear. The coarseness of the hay keeps their teeth ground down and healthy. This need to keep their teeth healthy should never, ever be underestimated. It is very important for capybara teeth to be kept in check, as the teeth would be in the wild grazing on coarse grasses. I have seen capybaras chewing on twigs, bark and stones as a method of self-help dentistry. Capybaras may grind their teeth when they sleep, which also helps keep their teeth in check.

The Hay and Guinea pig feed should be available 24/7.

Capybaras I know have some Orchard/Timothy hay mix in the living room. Whenever the capybaras want to chew on something, or they feel hungry, they go to the hay (or guinea pig feed). This means they do not chew pillowcases, plastic, comforters or any other inappropriate items of furniture. Swallowing plastic is potentially very dangerous.

The best treatment for diarrhoea is a probiotic. In America this probiotic is called Benebac. In Japan, zoos use a probiotic called Bio 3. This probiotic could be a lifesaver.

Bene-bac

Many people with capybaras and guinea pigs believe the probiotic ‘Bene-bac’ is a lifesaver. Some friends use it whenever the capybara’s poos become softer and sausage shaped, rather than the encapsulated, olive shaped faeces which capybaras living in their natural habitat pass. Bene-Bac Small Animal Powder is a concentrated live culture of four common digestive bacteria found in the intestinal tracts of mammals. Bene-Bac is recommended any time an animal experiences stress from changing nutritional or environmental conditions. Contains 20 million CFU per gram of viable lactic acid producing bacteria. Powder formula is easy to mix with water.   It comes in 4 different types – the Bene-bac designed for guinea pigs is the correct one to use.

Constipation: Bene-bac can also be used to treat constipation. It is important to ensure your capybara drinks enough water and has access to fresh water to drink 24 hours a day. A healthy diet of unrestricted access to fresh grass should ensure a capybara does not become constipated. Chewing coarse grasses is essential for the health of capybara teeth. You should always consult your vet as soon as you become concerned.

Critical Care Formula for Capybaras. Capybara Health Care. This Formula Could Save the Life of Your Capybara.

If you have a capybara who is not eating properly, or becoming very thin, this nutritional formula made by Oxbow, Critical Care for Herbivores, is recommended by a vet who specialises in treating capybaras. Your capybara may have tooth problems (which will need to be attended to) which makes chewing painful, or he might have an illness, or be recovering from surgery. This product has everything a capybara needs for optimum nutrition and health and recovery.

Remember that if your capybara has not been eating very much, his stomach will have shrunk. This means he will only be able to eat small quantities of food at any one time. You will need to keep offering him this formula, in small quantities, throughout the day to ensure he gets adequate nutrition.

Critical Care for Herbivores is a high protein, high energy, high fibre, easily digested powdered formula, with all the essential vitamins and minerals.. It is designed to be palatable so that your capybara enjoys it and wants to eat. It contains high-fibre Timothy hay to support proper gut physiology and digestion. It comes as a powder to be mixed with liquid.

A Critical Care Formula in the form of a crunchy “biscuit”, is also available, and chewing it will be good for your capybara’s teeth.

For more information please see the link below:

            Excessive mucus in faeces may be a sign of a bacterial infection, a blockage or tumours. The gut and intestines rely on a certain amount of mucus to function normally. Excessive amounts of mucus could indicate a blockage. This could be caused by anything from a foreign body to a bad diet with not enough roughage to keep the tract moving. Dehydration and constipation can also cause an increase in mucus. You should definitely consult your vet.

A constant intake of high fibre, low calorie grazing, grass or hay, is essential to keep the capybara’s intestinal tracts from slowing and going into stasis. Fruit might cause fermentation in the gut which can lead to bloat. In guinea pigs this is a big killer and often very hard to reverse. Fluids, fibre and lots of grass can be used to treat this.

A leading rodentologist in Britain recommends a sheep wormer, or genetically similar product, be used on guinea pigs and grazing animals for digestive health.

The U.S. Navy, the US Police Force and the best animal trainers do not use food as a reward. In the words of one US naval dog trainer “food complicates training”. Capybaras are highly intelligent. In the opinion of many capybara owners they are at least as intelligent as the most intelligent dogs. They are also highly sophisticated emotionally; i.e. they have high emotional intelligence. They respond very well to praise, and are very sensitive to the tone of voice, with a surprisingly large vocabulary. Instead of using food as a reward, use praise, such as “Good Boy together with the capybaras name”. The capybara will swell up with pride. This is far more rewarding to him than a sweet toxic food treat.

A new study suggests that most dogs respond more positively to praise than to food.

One danger with giving capybaras inappropriate food treats is that they may soon only do what you want in return for a treat. If it is a high energy treat they may no longer eat the copious amounts of grass and hay that they need to maintain a healthy digestive system.

Capybaras are highly emotional animals and do not react well to stress, which can lead to digestive problems. In the wild capybaras have the support of the herd, and close proximity to other herd members, for their emotional well-being. I have never met a pet capybara who is bonded with humans who did not suffer. Every time the human, with whom the pet is bonded, leaves the home the capybara suffers acute separation anxiety. This is something I have witnessed many times and it is absolutely heartbreaking. The light goes out in the capybara’s eyes as the human he loves disappears out of view. The capybara will sit for a long time facing in the direction his loved one departed in. The capybara may sit by the entrance gate or front door waiting for his beloved human to return, and call and call.

A capybara bonded with a human will view this human as a herd member. This reaction to separation and the disappearance of a herd member probably reflects 30 million years of evolution wherein a lone capybara, abandoned by the herd or separated from it, would have little chance of survival.   If you are going to live with a pet capybara it would be kinder to let the capybara bond with another animal who will remain at home all day with the capybara, rather than have him/her bond with you and suffer everytime you have to go out (to work, shopping etc).  A Mara or a calm dog such as a labrador or border collie might be the ideal companion.

(for further information about Wombaroo Baby Capybara Milk Replacer, see the end of this blog)

Rodents are addicted to sugar and sweet foods (more so than cocaine!). This is another reason I would be very careful about introducing anything sweet into a capybara’s diet as this can lead to the capybara becoming curious about other unhealthy foods which he/she had never shown any interest in before.

This is the information Kapi’yva Exotics, a leading breeder of exotic animals, provides for capybara diet on its website:

“Capybaras are true herbivores, their diet in the wild consists almost exclusively of various grasses. In captivity, their diet should consist primarily of guinea pig or livestock feed and plenty of fresh grass or hay. Capybaras do not naturally produce adequate amounts of vitamin C and they can develop scurvy as a result of vitamin C deficiencies. In the wild the large amounts of fresh grass they consume provides the extra vitamin C they need. In captivity, their diet must contain either plenty of fresh grass for grazing or a vitamin C supplement. Most commercial guinea pig diets will contain a vitamin C supplement but these can be very costly if you are feeding multiple adult capybaras. Mazuri and LabDiet guinea pig formulas are available in 25lb and 50lb bags and can be found at, or specially ordered at most feed stores. A much cheaper alternative is livestock or rabbit feed. If used as a staple diet extra vitamin C should be added. The easiest method I’ve found of doing this is to dust or mix their feed with ascorbic acid powder.

I DO NOT recommend feeding fruits, vegetables or other items containing large amounts of sugar on a daily basis. There is some evidence that diets containing large amounts of sugar, even from healthy sources, can cause liver and heart problems.

They have evolved as grazers, feeding primarily grass/hay and guinea pig feed is the best way to mimic their natural diet.”

Some people give horse feed instead of guinea pig pellets primarily for reasons of cost. It is important to read the ingredients of any formula feed as this will dictate your choice.   As horses are considered more valuable than cattle, horse feed is likely to be made of more high-quality ingredients.”

Below I include some information on what not to feed and why. The information comes from exotic pet vets and experienced capybara owners who have done a great deal of research.

Grazing on Unknown Grass: One capybara owner wrote: “We are very cautious about feeding unknown grass. Our rule of thumb, is that if it’s long and neglected, we’ll try it. If it looks too well taken care of, we fear poisons and leave it. It is more likely that fertilisers and weedkillers will be applied to well cared for grass. You also have to always check grass for toxic weeds. We have nightshade in this area. I don’t even know if they would actually eat it, but I’m very cautious.  Water effects fertilizers, but that would not be my main concern. I worry about insecticides and herbicides, which are usually designed to have residual effects that erode over time, not by water.”

Alfalfa:  An exotic pet vet at a leading university veterinary school is quoted as saying ” Absolutely no alfalfa, it is too rich.”  It may also be too high in calcium.

Calcium:  “There may be a concern about too much calcium for rodents and animals who extract extra nutrients through hindgut fermentation, this includes capybaras. There may be a risk of bladder stones or grit from excess calcium. Here’s a hay chart on calcium levels: http://www.guinealynx.info/hay_calcium.html “.

Vegetables:  The Capybaras at Nagasaki Bio Park, some of whom lived to a ripe old age, at least 13 years, were fed vegetables in season. When I was there it was cabbage, carrots and pumpkin. The capybaras at the Bio Park who eat the most carrots do not produce healthy olive shaped faeces. The faeces associated with parents is soft, barely even sausage shaped.   One capybara owner had this to say about carrots: “I have read online that the sugar level in carrots is on a par with apples and that because of the fat soluble vitamin A, if fed too much (or in a combination with other sources like alfalfa) the vitamin A can build up to toxic levels. She feeds one carrot a day.”

Sweetcorn: every Exotic Pet Vet with experience of capybaras was unanimous in saying you should not feed sweetcorn to capybaras. It is far too sweet.

I would remove all seeds and berries from my garden/yard as soon as they fall from trees.

Below is some information taken from research done on capybaras in the wild in South America:

This excellent book, see link below, is a collection of research papers on capybara, unfortunately finance for research comes from the agricultural industry so that is the primary focus of the research, but there is still a lot of very useful information:

http://www.springer.com/life+sciences/ecology/book/978-1-4614-3999-8

The capybara, Hydrochoerus hydrochaeris, is a herbivorous semi aquatic mammal that grazes near water. A number of physiological and morphological adaptations of the capybaras digestive system allowed this species to meet its energy requirements from a diet with a high fibre and low nutritional content and silica deposits.

These highly fibrous diet components are extremely difficult to digest, therefore herbivores possess specific adaptations for the digestion of these materials. The best known and most common adaptation to a high fibre diet among mammals is fermentation by symbionts (by bacteria and fungi and protozoa), coupled with mechanisms for the digestion and absorption of the products of fermentation. Among mammals there are two distinct types of symbiotic digestion where fermentation occurs. 1) foregut fermentation, as found in cows, and 2) hindgut fermentation as found in rodents.

Hindgut fermenters use the cecum, located between the small and large intestines, as a fermentation chamber, which precludes regurgitation and re-swallowing the fermented plants as a strategy for the absorption of nutrients. In the case of the capybara the process of cecotrophy allows a daily cycle of feeding and reingestion: food goes once along the digestive tract, entering the cecum where it is fermented and then excreted. These excreted products are taken directly from the anus by the herbivore and they pass one more time through the entire digestive tract.  The waste products bypass the cecum and move onto the large intestine, where hard dry faeces are excreted (but not reabsorbed this time). The two processes occur within a 24 hour cycle. It has been argued that, since hindgut fermenters can take advantage of any available directly digestible (i.e. non-fibre) nutrients before the bacterial fermentation takes place, they are more efficient at extracting nutrients from food than foregut fermenters.

The capybara diet, in the wild, consists mainly of grasses, aquatic grasses with varying a portion of sedges and just a few other plants. Capybaras gnaw on the bark of bushes and trees. Bark is nutritious and keeps their teeth healthy and in check.

During the wet season when plants are more abundant, capybaras are more selective and spend more time grazing on Hymenachne amplexicaulis, an aquatic grass of high caloric and low fibre content, then on less palatable reeds.

Capybaras are considered predominately diurnal, however groups have been observed grazing during the night.

In the tropics, capybaras spend 31% of their time grazing during the wet season, and 42% in the dry season.

The 3 products below could be life-saving for your capybara:

The Sounds Capybaras Make. Capybaras’ Vocalisations, Calls and Barks サウンドは、カピバラメイク。カピバラ発声、呼び出し、樹皮

Capybaras are a very vocal species and vocal communication is very important to them in terms of regulating social encounters and alerting other members of their herd to what is happening in their environment such as the presence of predators or babies becoming isolated from the herd.

Capybaras are very gregarious and frequently vocalize. Some of their vocalisations are outside the range of human hearing at ultrasonic or infrasonic levels. Capybaras also communicate through body language and smell. Capybaras have very high olfactory and emotional intelligence.

Hinase Momiji 在長崎生物公園的等級中排名第一和第二。 他們是最好的朋友,一起玩耍,一起睡覺,互相跟隨。 紅葉通常領先,但在食物方面,日瀨總是獲勝。 在這段視頻中,他們互相呼喚,似乎在說來和我一起在池塘里玩吧

ヒナセとモミジは親友です。長崎バイオパークヒエラルキーで1位と2位.  Hinase, number 1 in the herd hierarchy, and Momiji, number 2 in the herd hierarchy, are the best of friends. They play together in the pond every day for several hours, guard the entrance to the Onsen in winter and sometimes they won’t allow any other capybara to enter the Onsen. They often call each other, often a strident “come here” vocalisation, especially when one of them is in the pond and wants the other to join her. On hearing the “come here” call the other capybara will usually swim over, but not always. Momiji is a very intense capybara and her call sounds particularly urgent and strident. Momiji usually leads when they go off together, and takes much more interest in herd activities. Where food is concerned Hinase always wins. Hinase can be a bit of a bully and when they are playing in the pond she usually rides on Momiji and sometimes becomes aggressive, at which Momiji swims away quickly but soon returns so she must know Hinase’s aggression will be short lived. Hinase gets very frustrated because despite being number 1 in the hierarchy she is not allowed to mate with Kona, the breeding male, who is in a separate enclosure. Aoba, Momiji’s daughter, should be the next female capybara to mate but the current chief capybara keeper has no understanding of capybara behaviour or capybara husbandry and chooses the female capybaras who will allow her to “interfere” with the pups as soon as they are born.

Capybaras make the most beautiful sounds and vocalisations. When they are happy, or pleased to see you, they make a soft, chuckling sound known in academic circles as “click call”.

A Capybara chorus, when a number of capybaras sing in unison, is truly magical.

In the video below you can hear a herd of female capybaras singing in unison. Capybaras make the most beautiful vocalisations when the females sing to the males and the males sing to the females. In this video the female capybaras set off en masse to visit Toku, the male capybara. This procession may start when a very high ranking female capybara, it used to be Donguri, sets off towards Toku’s enclosure. She will sometimes bark to announce her departure and she very often makes a deep, gruff call. Toku also often sings when they arrive. When they arrive at Toku’s enclosure some of the capybaras rub their morillos on the fence of his enclosure or on the rope barrier just before the entrance to his enclosure. This morillo rubbing is usually done by the most senior capybaras in the hierarchy, Donguri, Hinase, Maple, Momiji and Zabon, although Ryoko, Aoba and some of the younger ones also rub their morillos.

This is the sound of a very happy capybara: Tuff’n is one of the most vocal capybaras I have met. When he was a young pup Tuff’n sometimes vocalised for much of the day; a juvenile i.e., very young capybara does this vocalisation to keep in touch with his herd and to let the herd know where he is.  Tuff’s herd was Romeo.  Now that he is an adult Tuff’n only “sings” for specific reasons, for example, in anticipation of being petted or being given food, making his ‘happy sound’ (click call) as he wanders round the house, or when he is eating or even when he “poohs”! Tuff’n is a hedonist and loves to be pampered or to laze all day in the sun. He has a very loud voice as well, even though, in this video, he is still just a 2-month-old baby. Sometimes his happy call is interspersed with a shrill call, as in this video. Tuff’n is bonded to Romeo, whereas Romeo is bonded to the humans he lives with. Tuff’n becomes very anxious if he doesn’t know where Romeo is. Romeo becomes very anxious if his humans leave the home.

2. The sound of a whole herd of capybaras singing in unison is truly magical. Here you can hear the herd singing loudly in the background as you watch young Yuzu slipping about as she tries to scratch herself on a slippery, mossy ledge in the pond.カピバラの群れの曲の全体的な音が一斉に素晴らしい、本当に魔法です。ここでは、滑り若いゆずを見ることができます。彼女は苔むした、滑りやすい棚の上に自分自身を傷つけしようとします。池の中

Here is another video of fifteen Capybaras singing in unison. Everything comes alive with the magical sound of Capybaras. This chorus goes on for up to half an hour or longer. Some afternoons we were treated to this chorus on at least two or three occasions over the course of the afternoon, other afternoons no chorus at all. After watermelon time, one or two capybaras make their escape to the freedom of the pond, while the others remain in the petting area. Then the chorus starts as the capybaras begin to think about moving en masse into the water. After about 10 minutes the exodus begins. The four youngest tend to be reluctant to leave since they get the most pampering and feeding, and they know that if they stay behind every visitor who comes into their enclosure will buy some bamboo or at least one container of ‘Capybara’ pellets to feed them.

最大限に音を上げてください Please turn sound up to maximum
斉に歌っている15頭のカピバラたち、これほど不思議な光景はありません。すべては、カピバラたちの不思議な音声で盛り上がっています。 このコーラス(合唱)は、少なくとも30分に及んでいます。

3. The sound a capybara mother makes as her babies suckle is truly magical. She goes into a trancelike state, her eyes glaze over and she starts to “sing”. She relaxes and seems to be very happy. Based on my observations it seems to me the sensation of the babies suckling at her teats maybe a very pleasurable one for a mother capybara.

4. This is the joyful sound of capybaras romancing: Female capybaras rub and nibble the male capybara and vocalise:

5 At the start of this video Kaede, a female capybara, emits a series of calls. Kaede frequently escapes from the enclosure, but unlike the other capybaras who like to escape, she doesn’t always go to the lush green grass near the enclosure. She often goes to visit Ran, a male capybara all alone in a tiny pen nearby. She sits against the wall of his pen and he comes over to be as close to her as possible on the other side of the wall. They cannot see each other because of the solid wall. Kaede is low down in the female hierarchy so perhaps she sees her chances of mating with the very desirable Yasushi as slender and is setting her sights on Ran instead.

The capybaras sitting by the gate in the video are all hoping to escape. It tends to be the same capybaras all the time who like to escape. Yasushi is the magnificent long-haired male in this video, showing an interest in some of the females; you will notice that the females are also showing an interest in Yasushi by sniffing his rear end and his testicles. He is always the centre of attention for the female capybaras at Nagasaki Bio Park.

“ビデオの始まりはカエデから(2008年9月10日に生まれた雌のカピバラ)は一連の囁きを発します。私は彼女が何を言ったのか、囁いたのか、知っていいればと思います。カエデは、一番の脱出の名人。(カピバラのエリアから)しかし、逃げるのを好む他のカピバラとは異なり、彼女は構内の近くの青々とした緑の芝生に必ずしも行きません。 彼女はランを訪ねにしばしば行きます。そして、オスのカピバラの近くで小さな囲いの中で一人きりで居ます。彼女はオスのカピバラの反対側に座ります。そしてオスは、出来るだけ親しくしようと近寄ってきます。カエデは、女性のカピバラ階級の中では下位にいます。おそらく彼女はヤスシと結婚する可能性を感じいますが、、ランにも興味を持たせるようにしています。ランはたぶん生物学的にみると、将来パークのカピバラのボスになる存在でしょう。                                                                                        ビデオの中で門のそばに座っているカピバラのすべては、逃げることを望んでいます。 誰が逃げるのが好きかは、常に同じカピバラである傾向があります。 ヤスシはこのビデオの中の素晴らしい長髪のカピバラです。そして、女性の何人かに対する関心を示します。あなたは、女性が彼の後部と彼のピンク色の大事なところ(男性自身)のにおいを嗅ぐことによってヤスシに対する関心も示していると気がつきます。 彼は、常に長崎バイオパークの雌のカピバラの注目の的です

6. I believe this unusual sounding capybara vocalisation is sometimes a sign of frustration. This vocalisation is usually made by very high ranking females and breeding males. Donguri makes this call when she wants to visit the male capybara, Toku, however he is in a separate enclosure and she cannot be with him. Hinase and Momiji, number 1 and number 2 in the Bio Park hierarchy, frequently call each other like this, to come to them.  In summer, they often do this at around 1 pm to play in the pond or to go to visit the breeding male.

On the occasion shown in this video Donguri has already made this strange vocalisation several times. It is barely audible the second time (after about 28 seconds). She is calling to Momiji who is in a separate enclosure with her three babies. Donguri is Momiji’s mother. In the wild Donguri would have access to all the capybaras in the herd including her grandchildren and great grandchild, so it must be very upsetting and frustrating for her that she cannot get to them. Donguri also got very upset when a film crew entered Momiji’s enclosure and Momiji became very stressed. Donguri makes the same call when she hurries over to Toku’s enclosure. She has been rubbing her morillo and marking and urinating in Toku’s presence so she may be coming into oestrus.

This is a very interesting sounding call.  I have never seen reference to it in research papers on capybara vocalisations.

The Bark:

8.  Capybara Alarm Calls “Danger Humans” カピバラアラームが呼び出し「危険の人間」

Most afternoons at about 4 PM Goemon, a 4-year-old male capybara who was born at Nagasaki Bio Park and is in a separate enclosure to keep him apart from the females, makes the most compelling, frantic calls. (see video below)!

In the video below, Syu repeatedly makes this alarm call (whistle) alerting the rest of the herd.

9. Tooth Chattering 歯のチャタリング

You can hear and see tooth chattering just after 1 minute and 8 seconds and again for longer at about 1 minute and 32 seconds. Yuzu is doing the tooth chattering. She has been put in a separate enclosure because six of the capybaras in the main herd attacked her. I was told she doesn’t defend herself which is why these capybaras pick on her, but I don’t know if that is accurate.

 This is the anxious call/vocalisation of a baby capybara. In this case little Donut has lost his mother, Momiji. Momiji hears his cries and comes looking for him, then Donut and brother Choco suckle.

10. The Appeasement Call/Vocalisation: this is the call made by a subordinate capybara who is being chased or attacked by a more senior capybara. In essence it is saying “please don’t attack me, I am no threat to you, I respect your place in the hierarchy”. I have seen no reference to this vocalisation in research papers. 

Alarm Calls and Distress Calls

When Aoba was injured she went into hiding in the pond under the boardwalk at Nagasaki Bio Park. When she still had not appeared the next morning the keepers became anxious and called her to come out with no response. Aoba’s mother, Momiji, understanding the situation then began calling frantically to her five-year-old daughter. About 10 minutes later Aoba swam out. I found this extremely interesting; it showed how strong the relationship between mother and daughter capybara was and what an exceptional mother Momiji was. You can see this in part of the video below:

Capybara Facts and Information (Hydrochoerus Hydrochaeris).

The capybara has attracted the attention of explorers and writers to South America from the 16th century onward. They were struck by both its size and its gregariousness and relative tameness. The capybara is the last survivor of a long line of gigantic grass eating rodents that evolved in South America over millions of years. The salient feature of capybara behaviour is undoubtedly their gregariousness.   It is the world’s largest rodent.

Scientific name: Hydrochoerus hydrochaeris.

NWN Aoba 18 Sep 2015 126

In the past capybaras were also known as Water Pig.

The name, capybara, originates from a word in the language of the indigenous Tupi people (ka’pii which means grass + gwara which means eater). The language of the Tupi was the most widely spoken language in South America in the 16th century and means grass eater although the translation “Master of the Grasses” is more poetic and reflects their diet and to some extent their habitat. There are many, many different names for the capybara in South America, the most common of these include: carpincho, capivara, chiguire, ronsoco.

There are 2 species of capybara:    The less common species is the Lesser Capybara (Hydrochoerus Isthmius) found in eastern Panama, northwestern Colombia and western Venezuela. This is a scientifically distinct species with anatomical differences, a smaller size and genetic differences. The species is fairly common in Panama but increasingly rare in Venezuela. It is threatened by subsistence hunting, the destruction of forested areas and the drainage of swamps. The Lesser Capybara breeds year round, with an average litter size of 3.5 pups. Individuals may be diurnal or nocturnal and solitary or social depending on season, habitat and hunting pressure.

Geographical Location:   Capybaras, Hydrochoerus hydrochaeris, are found in Central and South America from Panama to Northern Argentina primarily east of the Andes. They inhabit several types of wetland including gallery forest along rivers, mangroves and marshes. Capybaras reach their highest densities in the seasonally flooded savannas of the Llanos of Venezuela and Colombia, and the Pantanal of the Mato Grosso and on Marajo island in Brazil. They are always found in close proximity to water. The highest altitude at which capybaras are found is 4, 500 feet (1500 m). The only South American country with no capybaras is Chile.

Size and Weight: An adult capybara is large! Adult capybaras weigh on average from 40 to 50 kg in the wild (range 35 – 65 kg). In captivity the average weight is between 50 – 60 kg for a healthy capybara. There is no difference in weight between the sexes, but there are differences in size across the capybaras’ geographical distribution, with capybaras in Venezuela smaller than those of central and south eastern Brazil and Argentina, and those found in north-eastern Brazil being smaller still. In length they average about 4 feet (1.2 m) and are up to 2 feet tall (.60 m).

Physical Description:   Capybaras’ skin is thick and sparsely covered with coarse, oily water-resistant fur, varying in colour: red, grey, brown and straw coloured. Some black hairs can be found on the face, rump and limbs.

NWN 40% crop Syrup Q best sparse hair 28 Dec 2016 070

Capybaras have very coarse, sparse hair which dries very quickly

Capybaras have a vestigial tail but this is not visible from a distance. The front legs are shorter than the hind legs. The feet are partially webbed with four toes on the front feet and three toes on the hind feet. The head is large with the nostrils, eyes and ears (which are small and sparsely covered with short hairs, with a mobile fold that closes the ear canal when they submerge) located on the top of their head, so they can hear, smell and see while remaining almost completely submerged, an adaptation to their semi aquatic lifestyle which allows them to keep a lookout for any dangers while remaining almost invisible.  You can see this in the video below:

Semi aquatic lifestyle: Access to water is essential for capybaras. Capybaras’ territory always includes water which is used both as a refuge from predators and to control body temperature. They often seek refuge in water to escape predators (except the Cayman, which will rarely attack a capybara on land, but will often attack a capybara in water).  A Jaguar has to be within 3 feet of a capybara to have a chance of a successful attack.

The Capybara Scandal

I am trying to stop capybaras becoming the next “must have” exotic pet craze, and suffering the same fate as potbellied pigs, when they become large and difficult to handle.

I was talking to a lady who runs an Animal Refuge in Indiana who already has 2 capybaras who she rescued. She said there was a growing number of people buying female capybaras in order to mate them, and make money out of selling their babies. She expects to have many more capybaras who need to be rescued, because there are now so many breeders, and so many people who want a cute pet capybara.

When capybaras are portrayed as “cute” (dressed in clothes, hats and sunglasses) you create a market for pet capybaras among people who are not really interested in capybaras, but just love their cuteness. These people have no understanding of a capybara’s needs, and no desire to spend time doing the necessary research.

Capybaras are happiest as part of a herd in their natural habitat. These capybaras are in the Llanos of Colombia

People need to know that pet capybaras are sometimes aggressive. As they grow older and bigger, capybaras become very powerful. They have very sharp teeth (the Amerindians, in South America, use capybara teeth as weapons, attached to poles). Not many people want a pet who can cause painful, even serious, injuries.

Please see my blog: A Pet Capybara: Should I Have One?    https://capybaraworld.wordpress.com/2013/02/20/a-pet-capybara-should-i-have-one/

The leading breeder of capybaras stopped selling capybaras to the public as pets, about 8 years ago, because so many pet capybaras suffered, often dying prematurely or ending up in animal refuges.

This is the perfect enclosure for a capybara: lots of grass and a large pond. Photo by Martin MurmelTier Hees

Many pet capybaras die prematurely due to tooth problems, inappropriate diet and stress.

A friend, who runs an animal refuge, reminded me of the craze for potbellied pigs, not so long ago. When these potbellied pigs grew larger, many were abandoned and ended up in refuges. The same is beginning to happen with capybaras.

Capybaras are very sensitive emotionally; they are intelligent, sentient beings who can think and feel.

If you look in Ran’s eyes you can see how frightened he is

I was heartbroken to learn that during the extreme cold spell in February 2021, many pet capybaras suffered frostbite. This indicates that most people who get pet capybaras should not. This has happened before. Over the years I have been horrified to hear of capybaras suffering frostbite in North America. If I had capybaras living outside in extreme weather conditions, I would usher them into my house, and if necessary cover them with blankets. No capybara should suffer frostbite.

I find it very depressing that people who say they care about capybaras like to see capybaras dressed in clothes. No one who dresses a capybara in clothes should have one of these remarkable animals.

It seems that most people cannot see life from an animal’s perspective. Like everyone who understands animals, I don’t understand why people like seeing capybaras in dresses. One of the reasons people love capybaras is they are so cute – naked!

People should know that capybaras don’t like wearing clothes. This should not come as a surprise to anyone who understands animals. I have witnessed first-hand how uncomfortable and unhappy capybaras are in clothes. Being made to wear clothes also interferes with the relationship between a pet capybara and their owner. The capybara is confused why someone they love is doing this to them.

I came across a website, by accident, which advertised capybaras for sale. These were capybaras who had outgrown their “baby” cuteness. They varied in age from about nine months to 3 years. The way in which they were described by the people selling them was heartbreaking. One seller described his capybara as “Sold as is, with defects”, as if he was selling a used car. Another advertised his capybara as: “Cannot be handled”; I wondered what had caused this capybara to become so unhappy and aggressive. Another seller described the capybara he was selling as “Suitable for display” as though this sensitive, living being was an inanimate object with no feelings or needs. I was in tears thinking about the unhappy lives humans had created for these loving animals. And I was appalled at the lack of compassion, concern or morality of the people selling these unwanted capybaras.

I was in conversation recently with a man who wanted to keep a capybara as a pet. He was convinced he could give the capybara a better life than the capybara would experience in the wild! Research has shown that wild animals kept as pets suffer much more stress than if they were living in the wild, in their natural habitat.  I was horrified at this man’s lack of understanding and arrogance. He obviously had no understanding whatsoever of animals, and unfortunately was not interested in learning.

Capybaras do not like to wear clothes. Dressing a pet capybara causes stress and interferes with the bond between the capybara and the human, as the capybara cannot understand why the human is doing this to him
Capybaras do not like to wear clothes. Dressing a pet capybara causes stress and interferes with the bond between the capybara and the human, as the capybara cannot understand why the human is doing this to him

It is well known that the market for “cute” animal photos and videos is detrimental to Animal Welfare. In some countries it encourages people to buy wild animals as pets when in fact these wild animals are totally unsuited to becoming pets and usually suffer. It also results in an increasing number of zoos, often very small and cramped, which house cute animals in prisonlike conditions. These animals suffer immense stress in small, unsuitable enclosures, often with concrete floors. In the case of capybaras, who are semi aquatic, their water source is a small plastic tub often barely larger than the capybara himself, when they need a body of water large enough for them to swim and play.

Capybara cafes should be banned. A cafe is a very stressful and unsuitable habitat for a wild animal. Animals in captivity should always be able to express their natural behaviours and have some control over their lives. Capybaras need to have access to grazing and a pond 24/7. Nobody who understands animals would want to see a capybara, or any other wild animal, in a cafe.

We humans cause so much suffering to the animals we call “cute”. Capybaras, and all other species, are so VERY MUCH MORE than cute.

For more on this topic see my blog: “Animal Manifesto, Animals Are Real Not Cute”

https://capybaraworld.wordpress.com/2018/01/01/animal-manifesto-animals-are-real-not-cute/

Anyone who understands animals and cares about capybaras will be very concerned about the welfare of the growing number of capybaras being bought as pets.

There is an increasing number of people breeding capybaras for sale as pets to meet this demand. The result is capybaras suffer, and end up in refuges.

Some of the people who say they love capybaras, understand animals and care about the welfare of capybaras. Other people who say they like capybaras, just like their cuteness and want them as entertainment, but have no understanding of, or interest in, their welfare. Unfortunately, I believe the majority of people who say they like capybaras, are in the latter category. I believe this is partly because most people cannot see life from an animal’s perspective. My mission is to prevent capybaras from suffering by helping people to understand the needs of these remarkable, sentient beings.

What Should I Feed My Pet Capybara? Capybara Diet

 

Please see my latest blog about capybara diet:

Capybara Diet. Includes Treatments for Dietary Health Issues.

https://capybaraworld.wordpress.com/2021/10/10/capybara-diet-includes-treatments-for-dietary-health-issues-%e6%b0%b4%e8%b1%9a%e9%a3%b2%e9%a3%9f-%e3%82%ab%e3%83%94%e3%83%90%e3%83%a9%e3%83%80%e3%82%a4%e3%82%a8%e3%83%83%e3%83%88/

Includes details of Milk Formula specifically formulated for baby capybaras

A lady who has an Animal Sanctuary with capybaras, recently told me: “I do believe diet has killed most pet capybaras who die prematurely. People feed them a diet which is too “rich”, as well as other foods which capybaras have not evolved to eat. Some people feed dairy for the life of the capybara which is crazy. Many people also feed junk food, popsicles, other foods with sugar, too much fat, and too much food like corn and fruit. One person even fed her capybara toothpaste every day because he liked it! Toothpaste contains fluoride which is a toxin, and is used in rodent killer products. This lady’s capybaras are living to a ripe old age on a diet of: Hay, grass, bamboo, some vegetables and sometimes sweet potato, and very occasionally fruit. They also get guinea pig pellets or rabbit pellets daily, and extra vitamin C. They have never been sick or had tooth problems.

Marvin and Elizabeth asked me to write this blog. They felt that when their first capybara came to live with them the information they needed was not available on the Internet.

Please Don’t Let Any More Capybaras Die Prematurely.

What Should I Feed My Pet Capybara?

This blog is written in memory of Templeton, a young capybara, the brightest of stars, who died far too prematurely when he was only four months old. Marvin and Elizabeth believe that his diet caused his death. They did not feed him junk food, but they did feed him a lot of corn and carrots which his young digestive system could not cope with

Put simply:  DO NOT FEED YOUR CAPYBARA ANYTHING THAT IS HIGH FAT, LIKE PEANUTS, SUNFLOWER SEEDS, OR BIRD SEED OR ANYTHING WITH ADDED SUGAR AND ABSOLUTELY NO CANDY or  JUNK FOOD, AND ONLY OCCASIONALLY  SWEET FRUIT.

Rodents are addicted to sugar and sweet foods. Another reason I would never introduce anything sweet into a capybara diet as this can lead to the capybara becoming curious about other foods which he/she had never shown any interest in before.

Templeton, So Full of Life and Oh So Cute. Here he is with Yellow Cat

Templeton, So Full of Life and Oh So Cute. Here he is with Yellow Cat

The capybara digestive system evolved over 30 million years to take advantage of a diet that was high in fibre and low in nutritional content. If you want your capybara to live a long and healthy life you should try to replicate this diet as closely as possible.

Sugar and Stress are two of the most potentially life-threatening causal factors a pet capybara can encounter. Capybaras should not be given anything with sugar in it like candy, ice cream, sweetened yoghurt, ice lollies etc. Neither should they be given junk food; this seems like common sense but it is surprising how many people, out of ignorance, will feed their pets whatever junk food they are eating. In addition, Exotic Animal Vets warn about the potential harm in feeding the naturally occuring ‘sugar’ in sweet vegetables and fruit, specifically mentioning sweetcorn because of the high sugar content, so you can imagine how disastrous any food with added sugar would be.

Templeton, So Friendly and Adorable

Templeton, So Friendly and Adorable

Animals do not have the same tolerance for unnatural feed that humans have. This is especially true in the case of a capybara, where its digestive system is exceptionally sensitive, and has been described by at least one expert as the ‘weak link’ in terms of capybara health. I know of at least two capybaras who died very prematurely, in one case after only a few months, because of diet.

The healthiest pet capybaras that I have met are fed a diet of fresh untreated grass, hay (Orchard Hay and Timothy Hay which are not too high quality), aquatic reeds and guinea pig feed.

The olive shaped, green, separated droppings  are a sign of a healthy capybara in the wild.  Softer, sausage shaped faeces are an indication that the capybara is being fed the wrong diet. Fruit, carrots, sweet corn etc may be responsible.

Please also see this blog for information about plants, chemicals and other potentially lethal dangers that capybaras may encounter:
https://capybaraworld.wordpress.com/2014/06/29/capybaras-beware-of-toxic-plants-chemicals-and-poisonous-animals-like-scorpions-and-snakes-humans-remove-these-from-your-land-garden-and-yard-%e3%82%ab%e3%83%94%e3%83%90%e3%83%a9%e3%81%ab/

HEALTHY TEETH:  To avoid your pet capybara ending up with very painful, life threatening (not to mention expensive) teeth problems, it is essential to include a lot of coarse grazing in a capybara diet.  Unlimited Fresh grass should be a staple part of every capybara diet.   Lower quality hay is more suitable for a capybara’s digestive system and means they will eat more, which equates to more fiber and more tooth wear. The coarseness of the hay keeps their teeth ground down and healthy. This need to keep their teeth healthy should never, ever be underestimated. It is very important for capybara teeth to be kept in check, as they would be in the wild grazing on coarse grasses. I have seen capybaras chewing on twigs and stones as a method of self-help dentistry. Capybaras may grind their teeth when they sleep, which also helps keep their teeth in check.

The Hay and Guinea pig feed should be available 24/7. In the case of Romeo and Tuff’n, there is a large bale of Orchard/Timothy Hay mix in the living room. Whenever the capybaras want to chew on something, or they feel hungry, they go to the hay (or guinea pig feed). This means they do not chew pillowcases, plastic, comforters or any other inappropriate items of furniture.

The best treatment for diarrhoea is a probiotic. In America this probiotic is called Benebac and in Japan, zoos use a probiotic called Bio 3. This probiotic could be a lifesaver.

Bene-bac

Many people with capybaras and guinea pigs believe the probiotic ‘Bene-bac’ is a lifesaver. Some friends use it whenever the capybara’s poos become softer and sausage shaped, rather than the encapsulated, olive shaped faeces which capybaras living in their natural habitat pass. Bene-Bac Small Animal Powder is a concentrated live culture of four common digestive bacteria found in the intestinal tracts of mammals. Bene-Bac is recommended any time an animal experiences stress from changing nutritional or environmental conditions. Contains 20 million CFU per gram of viable lactic acid producing bacteria. Powder formula is easy to mix with water.   It comes in 4 different types – the Bene-bac designed for guinea pigs is the correct one to use.

Constipation: Bene-bac can also be used to treat constipation. It is important to ensure your capybara drinks enough water and has access to fresh water to drink 24 hours a day. A healthy diet of unrestricted access to fresh grass should ensure a capybara does not become constipated. Chewing coarse grasses is essential for the health of capybara teeth. You should always consult your vet as soon as you become concerned.

Bene-bac Product Information

The best animal trainers do not use food as a reward. Capybaras are highly intelligent. In the opinion of many capybara owners they are at least as intelligent as the most intelligent dogs. They are also highly sophisticated emotionally. They respond very well to praise, and are very sensitive to the tone of voice, with a surprisingly large vocabulary. If you say to Romeo “Good Boy, Romeo”, he swells up with pride. This is far more rewarding to him than a sweet toxic food treat.

A new study suggests that most dogs respond more positively to praise than to food.

http://www.sciencemag.org/news/2016/08/dogs-would-rather-get-belly-rub-treat?utm_source=newsfromscience&utm_medium=facebook-text&utm_campaign=wantatreat-6517

The danger with giving them inappropriate food treats is that they will soon only do what you want in return for a treat. If it is a high energy treat they will no longer eat the copious amounts of grass and hay that they need to maintain a healthy digestive system.

Capybaras are highly emotional animals and do not react well to stress, which can lead to digestive problems. In the wild capybaras have the support of, and close proximity to the herd, for their emotional well-being. As house pets they suffer from separation anxiety to a very high degree if the human with whom they have bonded is not with them. This probably reflects 30 million years of evolution wherein a lone capybara, abandoned by the herd or separated from it, would have little chance of survival.   If you are going to live with a pet capybara it would be kinder to let the capybara bond with another animal who will remain at home all day with the capybara, rather than have him/her bond with you and suffer everytime you have to go out (to work, shopping etc).  A border collie might be the ideal companion.

This is the information Kapi’yva Exotics, a leading breeder of exotic animals, provides for capybara diet on its website:

“Capybaras are true herbivores, their diet in the wild consists almost exclusively of various grasses. In captivity, their diet should consist primarily of guinea pig or livestock feed and plenty of fresh grass or hay. Capybaras do not naturally produce adequate amounts of vitamin C and they can develop scurvy as a result of vitamin C deficiencies. In the wild the large amounts of fresh grass they consume provides the extra vitamin C they need. In captivity, their diet must contain either plenty of fresh grass for grazing or a vitamin C supplement. Most commercial guinea pig diets will contain a vitamin C supplement but these can be very costly if you are feeding multiple adult capybaras. Mazuri and LabDiet guinea pig formulas are available in 25lb and 50lb bags and can be found at, or specially ordered at most feed stores. A much cheaper alternative is livestock or rabbit feed. If used as a staple diet extra vitamin C should be added. The easiest method I’ve found of doing this is to dust or mix their feed with ascorbic acid powder.

I DO NOT recommend feeding fruits, vegetables or other items containing large amounts of sugar on a daily basis. There is some evidence that diets containing large amounts of sugar, even from healthy sources, can cause liver and heart problems.

They have evolved as grazers, feeding primarily grass/hay and guinea pig feed is the best way to mimic their natural diet.”

Some people give horse feed instead of guinea pig pellets primarily for reasons of cost. It is important to read the ingredients of any formula feed as this will dictate your choice.   As horses are considered more valuable than cattle, horse feed is likely to be made of more high-quality ingredients.”

Below I include some information on what not to feed and why. The information comes from exotic pet vets and experienced capybara owners who have done a great deal of research.

Grazing on Unknown Grass: One capybara owner wrote: “We are very cautious about feeding unknown grass. Our rule of thumb, is that if it’s long and neglected, we’ll try it. If it looks too well taken care of, we fear poisons and leave it. It is more likely that fertilisers and weedkillers will be applied to well cared for grass. You also have to always check grass for toxic weeds. We have nightshade in this area. I don’t even know if they would actually eat it, but I’m very cautious.  Water effects fertilizers, but that would not be my main concern. I worry about insecticides and herbicides, which are usually designed to have residual effects that erode over time, not by water.”

Alfalfa:  An exotic pet vet at a leading university veterinary school is quoted as saying ” Absolutely no alfalfa, it is too rich.”  It may also be too high in calcium.

Calcium:  “There may be a concern about too much calcium for rodents and animals who extract extra nutrients through hindgut fermentation, this includes capybaras. There may be a risk of bladder stones or grit from excess calcium. Here’s a hay chart on calcium levels: http://www.guinealynx.info/hay_calcium.html “.

Vegetables:  The Capybaras at Nagasaki Bio Park, some of whom lived to a ripe old age (at least 13 years) were fed vegetables in season. When I was there it was cabbage, carrots and pumpkin. The capybaras at the Bio Park who eat the most carrots do not produce healthy olive shaped faeces. The faeces is soft, barely even sausage shaped.   One capybara owner had this to say about carrots: “I have read online that the sugar level in carrots is on a par with apples and that because of the fat soluble vitamin A, if fed too much (or in a combination with other sources like alfalfa) the vitamin A can build up to toxic levels. She feeds one carrot a day.”

Sweetcorn: every Exotic Pet Vet with experience of capybaras was unanimous in saying you should not feed sweetcorn to capybaras. It is far too sweet.

I would remove all seeds and berries from my garden/yard as soon as they fall from trees.

Below is some information taken from research done on capybaras in the wild in South America:

This excellent book, see link below, is a collection of research papers on capybara, unfortunately finance for research comes from the agricultural industry so that is the primary focus of the research, but there is still a lot of very useful information:

http://www.springer.com/life+sciences/ecology/book/978-1-4614-3999-8

The capybara, Hydrochoerus hydrochaeris, is a herbivorous semi aquatic mammal that grazes near water. A number of physiological and morphological adaptations of the capybaras digestive system allowed this species to meet its energy requirements from a diet with a high fibre and low nutritional content and silica deposits.

These highly fibrous diet components are extremely difficult to digest, therefore herbivores possess specific adaptations for the digestion of these materials. The best known and most common adaptation to a high fibre diet among mammals is fermentation by symbionts (by bacteria and fungi and protozoa), coupled with mechanisms for the digestion and absorption of the products of fermentation. Among mammals there are two distinct types of symbiotic digestion where fermentation occurs. 1) foregut fermentation, as found in cows, and 2) hindgut fermentation as found in rodents.

Hindgut fermenters use the cecum, located between the small and large intestines, as a fermentation chamber, which precludes regurgitation and re-swallowing the fermented plants as a strategy for the absorption of nutrients. In the case of the capybara the process of cecotrophy allows a daily cycle of feeding and reingestion: food goes once along the digestive tract, entering the cecum where it is fermented and then excreted. These excreted products are taken directly from the anus by the herbivore and they pass one more time through the entire digestive tract.  The waste products bypass the cecum and move onto the large intestine, where hard dry faeces are excreted (but not reabsorbed this time). The two processes occur within a 24 hour cycle. It has been argued that, since hindgut fermenters can take advantage of any available directly digestible (i.e. non-fibre) nutrients before the bacterial fermentation takes place, they are more efficient at extracting nutrients from food than foregut fermenters stop

The capybara diet, in the wild, consists mainly of grasses with varying a portion of sedges and just a few other plants

During the wet season when plants are more abundant, capybaras are more selective and spend more time grazing on Hymenachne amplexicaulis, an aquatic grass of high caloric and low fibre content, then on less palatable reeds.

Capybaras are considered predominately diurnal, however groups have been observed grazing during the night.

In the tropics, capybaras spend 31% of their time grazing during the wet season, and 42% in the dry season.

Pet Capybara Pool Size. What Size Pool Does My Capybara Need?

 

I am afraid I have had to remove the photos as some nasty person has been removing the watermark from my photos and uploading them to the internet. It is illegal to remove the watermark.

 A recommended minimum size of pool/pond is 9 ft x 16 ft with a depth of 4 ft. The pool or pond should have a few shallow places where the capybara can sit and rest while still remaining mostly or partly submerged. If your pool does not have any steps or ledges that would provide this, you should put something like a plastic table in the pool for the capybara to sit on. Make sure it is securely anchored and does not tip over when the capybara climbs onto it.

A large, 8 foot, cattle tank is not sufficient, many people would say . There is no way a capybara can swim properly in something this small. And of course it is not very deep either.

Capybaras are outstanding swimmers and need a pool/pond that is at least 4 feet deep. They love to swim underwater and are very playful, rolling and turning. Capybaras can stay under water for up to 5 minutes.

In the wild capybaras spend much of the afternoon in water. Submerging in water is a way for them to thermoregulate, i.e. cool themselves.

NWN Romeo Swimming

Capybaras are very agile and graceful in water. A cattle tank is not big enough to allow them to express themselves physically and aquatically, as they would in the wild.   It is a wonderful sight watching a capybara swim, and roll, and play with gay abandon.

 

Please see my blog which gives information about the dangers to capybaras of letting capybaras use your swimming pool. I also give information about a recommended filter system to use to clean the water in your swimming pool.  It is recommended that you do not use chlorine.

Pet Capybara FAQs. The Questions People Always Ask

Pet Capybara FAQs. ペットのカピバラのFAQ。 (よくある質問)

I am afraid I have had to remove the photos as some nasty person has been removing the watermark from my photos and uploading them to the internet. It is illegal to remove a watermark.

Please also read my blog:

Part 1 and much of Part 2 by Marvin Reeder who lives with Romeo and Tuff’n. These are the questions Marvin and Elizabeth are asked every day when they take Romeo and Tuff’n to the park:

Tuff'n and Romeo make regular visits to Lake Mead to swim. They do have their own specially treated swimming pool at home, but in the wild they would enjoy a life with wide open vistas. Capybaras like most wild animals do not like to be confined. They hate fences and barriers.

1. What is that?   A capybara.

What is a capybara?  

(Polite answer):     A Semi-Aquatic Herbivore from South America.

(Straight answer):     The World’s Largest Rodent.

2. Do they make a good pet?     NO!

It is very hard to create an environment which is healthy and mentally rewarding for the capybara, and safe.

How to pet a baby capybara. Little 2 month old Cookie, Maple’s daughter and Butter’s sister, goes into a trance state when just the right spot is massaged in just the right way.

The best experience you may have with capybaras is at Nagasaki Bio Park. Please see my blog:  If You Want a Capybara to Sit in Your Lap Go to Nagasaki Bio Park.  あなたは好きですか?愛情カピバラ?あなたの上に座って?長崎バイオパークに行きます

.
3. Are they like a cat or a dog?    No!

They are like a toddler (human) with sharp teeth and an attitude.

Capybara society is very hierarchical. Male capybaras will challenge each other to become the dominant male. With their very sharp teeth this will result in cuts. If you're male capybara decides to challenge you for the dominant position you will get bitten. Capybara skin is much tougher than human skin so it will be very painful

4. Are Capybaras Dangerous?:     Capybaras have razor sharp teeth and can be unpredictable. They are after all wild animals.

Do they bite?      Yes, depending on circumstances. I know of several capybaras which have bitten their owners and are now in shelters. It breaks my heart to think how these capybaras have been failed by humans, who probably should never have lived with a capybara in the first place.

Our video: Even the Most Sweet Natured Capybara Can Turn Aggressive 甘い性格のペットカピバラは攻撃的になる
Romeo is the most fantastic Capybara as anyone who has seen the videos of Romeo kissing Elizabeth Ojeda-Reeder Romeo-Tuffn will realise. But capybaras are wild animals and you never know how your actions might play out in the mind of a wild animal. It’s too easy to show how incredibly adorable capybaras are. I’ve seen a couple of blogs lately suggesting capybaras make great pets. This is absolute rubbish and very irresponsible. Capybaras need an incredible amount of love, time and commitment. Very few people would be able to give this. Too many capybaras get rejected as they get bigger and older and end up in refuges or die prematurely.

There is an awful lot of misinformation and inaccurate information about capybaras on the Internet.

Romeo nibbles Marvin affectionately. Very few, if any, capybaras could be trusted in this way. Romeo is quite exceptional. Romeo knows that Marvin is number one in the hierarchy and occasionally Romeo challenges him and becomes aggressive. Marvin is powerful enough, and has many decades experience with animals so he has never been seriously injured. This might not be the case with most humans.

5. How much does IT cost?

The cost could easily exceed thousands of dollars, when you factor in vet’s bills. The time investment the capybara needs is often greater than the (substantial) financial obligation.

Romeo is marking a cushion (with urine, which does not smell) as he frequently does to enforce his territory. He doesn't like the smell of freshly washed cushions. You can see the stains from the faeces on the carpet, faeces is also used for marking. Since this photo was taken all the carpets have been ripped out. In the living room there are now 2 bales of hay instead of furniture. The capybaras eat a lot of hay.

6. Are they potty trained?

Yes and No.  They are easily potty trained as babies.  However, as they grow older they will probably want to mark their territory using urine and feces. Capybaras need/like to mark their territory (with pooh). Don’t plan on keeping a carpet! Slick surfaces, like tiles, are too slippery, capybaras don’t get good traction with their claws and find it difficult to walk on slick surfaces.

Please see our video: What Capybaras Do When No One Is Looking カピバラアクション。誰も見ていない   

   https://www.youtube.com/watch?v=CvtVm_wN2PY

 Romeo doesn’t like the smell of the furnishings especially after they’ve been washed. He needs to make the smells more interesting by marking (using urine and sometimes faeces – you can see the stains on the carpet from the faeces) them. And since there are 2 male capybaras he needs to establish his territory by marking. This should make you think twice about having a pet capybara! Capybaras have not evolved over millions of years to live in homes. Unlike dogs and cats who have had over 10,000 years of domestication in which to adapt to living with humans, capybaras’ natural lifestyles should be respected if they come and live with you. After all they never asked to be your companions. Fortunately Romeo and Tuff’n live in a home with a family who understand their needs, and understand that their needs must be paramount.

All the carpets have now been ripped out. It is quite natural for capybaras to mark their territory. It would be cruel to prevent them carrying out this completely natural activity. So for reasons of hygiene you will need to have a floor that is easily washed. However, it must not be slick and slippery, like a tiled floor, as capybaras would not be able to move around comfortably on this type of flooring. The main living room has had all the furniture removed. Now there are just 2 bales of hay for the capybaras to eat.

2. Do they make a good pet?

No!    Capybaras are wild animals whose natural behaviour is not suited to domestication. They are wired for certain behaviours. If you force them to behave by your rules you will destroy some aspect of their spirit and your relationship with them. They did not ask to come and live with you, therefore the onus is on you to adapt to them and to ensure their happiness. You need to establish a very strong bond and good rapport with your capybara so that the capybara wants to do what you ask. Even then, although the capybara may understand perfectly what you are asking them to do, they will only comply if it suits them.

Marvin and Elizabeth have ripped out all their carpets. The largest room in the house has been given over to the capybaras and is covered in hay which provides good traction for capybara feet and a soft nesting area to rest on. There are two large bales of hay for Romeo and Tuff’n to eat.

Capybaras are herd animals and will expect the human they have bonded with to remain with them at all times. They get very stressed and anxious if this human leaves the home. Therefore if you have to go out to work or you need to enjoy a busy social life, please do not even consider having a capybara.

Capybaras are exceptionally social, gregarious herd animals. They become extremely distressed if left on their own. In the wild if a member of their herd became separated it would mean almost certain death.
Capybaras are exceptionally social, gregarious herd animals. They become extremely distressed if left on their own. In the wild if a member of their herd became separated it would mean almost certain death.

Some of the issues you will face include: i) Ensuring the capybaras have access to enough grass. It is far better for their teeth for them to graze, than for you to provide them with ready cut grass; ii) Providing access to a pool which is large enough for them to swim in and sanitised in a way that will not harm the capybara (see my two blogs on swimming pool size and sterilisation, links given below); iii) Placing electrical/power cords out of reach of the capybara; iv) Making sure there is nothing a capybara, especially a baby capybara, can crawl under and hide out of reach (when a baby capybara first arrives at a new home it may well be frightened and try to escape from you).

As Marvin and Elizabeth say with regard to living with a capybara: “Often it’s the little things or something you might not think would hurt them, that you have to look out for. Capybaras are not designed to live in a house. Everything is dangerous to them. We as humans have to look ahead and make it as safe as possible. This is a learning experience for all of us”.

A capybara in a pen would be very unhappy. It would not be getting the social attention it needs, and capybaras are amongst the most social animals I have ever met. In the wild their territory extends over many hectares (average size of territory in the wild is 5 – 16 hectares but can be much larger). To be confined in a cage of 100 ft.², (one Internet site suggests this size pen is appropriate!) would be like a prison. Capybaras don’t like barriers or boundaries.

Capybaras practice cecotrophy. This can get a little messy and you may find small amounts of cecotropes on your bed, sofa etc. The capybara diet is highly fibrous and nutritionally low in value.  Cecotrophy allows the capybara to digest more nutrients from an otherwise low nutrient diet and maximise the absorption of protein. The 'cecotrophy' excreta is different in composition to the usual oval shaped faeces, and contains up to 37% more protein and 30% less fibrous material, depending on the diet. Capybaras most often practice cecotrophy in the early morning hours when protein content is highest.

3. Are they like a cat or a dog?

No.   Capybaras are wild animals, they are not domesticated. Unlike cats and dogs they have not had more than 10,000 years of domestication in which to adapt to living with humans. There are people who feel that it is unkind to keep an exotic animal as a pet.

Capybaras are highly intelligent and very sophisticated emotionally. They will plan and strategise behaviours in order to get their way. If capybaras are frustrated or dissatisfied they may defecate on the carpet or in other inappropriate areas. They may pout or throw fits. They may well bite you.

Capybaras have very impressive, razor sharp teeth.  They can do a lot of harm and inflict a very painful bite if they choose to.

4. Are Capybaras Dangerous?   Do they bite?

Capybaras are very territorial and hierarchical. I know of many capybaras who have bitten the humans they live with because of territorial or hierarchical issues which their human did not have the skill, aptitude or knowledge to resolve.

If they are left alone they will become very stressed and unhappy which can lead to bad behaviour and biting. I know of too many capybaras who were living in unhappy circumstances and resorted to biting to express their unhappiness. A capybara bite can be very serious as they have razor sharp teeth.

Capybaras love to roll in the mud. It is an essential activity for the health of their skin. Although you may try to keep them out of the house until they have been washed, capybaras are very clever and devious at finding a way into your pristine house. Another reason not to have carpets.

5. How much does IT cost?

When considering the cost of living with a pet capybara, you will need an exotic pet vet who is experienced in looking after capybaras. Exotic pet vets are expensive. If you do not follow the right diet you will have health problems and tooth problems. The vet and dental bills will pile up.

Capybara teeth keep growing and need to be kept in check by eating coarse food. In the wild the capybara’s diet consists of wild grasses, some sages and aquatic plants, and bark. Many capybaras chew on twigs or stones to keep their teeth in check. You should follow this diet as closely as possible as capybaras digestion has evolved over 15 million years for this diet.

Video: Adorable Clever Capybara Knows How to Keep Her Teeth Healthy:

The correct diet is critically important for a capybara. Due to the way capybaras digest food, hindgut fermentation, they should not be fed sweet things, even sweetcorn. “What Should I Feed My Pet Capybara?”: https://capybaraworld.wordpress.com/2013/02/11/what-should-i-feed-my-pet-capybara/

If you have a male capybara the cost of neutering will be about $700.

Capybaras need sun for the health of their bones. In the wild they live outside, of course, and are exposed to sun throughout the day. Several pet capybaras have suffered very serious problems with their bones as a result of being kept inside. One young capybara has bones which are in such a poor state that his vet has advised he should be put down.

El Torro Romeo. Every day Romeo and Tuff'n go to the park to graze for 2 or 3 hours. Capybaras' digestive system has evolved over more than 15 million years for a diet of grasses. In the wild capybaras spend between 31% (in the wet season) and 42% (in the dry season) grazing. If they do not get the right diet, with plenty of course material, they may get life-threatening problems with their teeth. They should never be given sweet foods or junk food. Photo by Marvin Reeder

6. Are they potty trained?

Baby capybaras are very trainable without giving treats. They respond very well to the reward of being told “Good Boy/Girl” by the human they are attached to. However as they grow older they very often begin to mark their territory with their morillo and anal gland, using urine and faeces.

They defecate on average every 2 hours. That means you will be cleaning the potty pan at least 10 times a day if not more. This is a messy and unpleasant task.

Romeo Marking His Territory (with urine). It is natural for capybaras to mark their territory. It would be cruel to prevent them from fulfilling their natural behaviour. They never asked to be your companions and live in a house designed for humans. Most people would not be prepared to alter their lifestyle to ensure the happiness of their exotic pet. For this reason they really shouldn't consider keeping a capybara as a pet.

Other things to consider:

Capybaras understand many words and phrases. You need to be the sort of person who is in tune with animals and able to communicate with animals in a respectful and loving way.

Capybaras are exceedingly cute, perhaps even more so when they are babies. However adult capybaras will take over the house. They are exceptionally smart and opportunistic. You will find yourself feeling bad that you haven’t made their accommodations better so as to fit in with their lifestyle.

Please see our video: What Capybaras Do When No One Is Looking カピバラアクション。誰も見ていない。

Romeo doesn’t like the smell of the furnishings especially after they’ve been washed. He needs to make the smells more interesting by marking (using urine and sometimes faeces – you can see the stains on the carpet from the faeces) them. And since there are 2 male capybaras he needs to establish his territory by marking. This should make you think twice about having a pet capybara! Capybaras have not evolved over millions of years to live in homes. Unlike dogs and cats who have had over 10,000 years of domestication in which to adapt to living with humans, capybaras’ natural lifestyles should be respected if they come and live with you. After all they never asked to be your companions. Fortunately Romeo and Tuff’n live in a home with a family who understand their needs, and understand that their needs must be paramount.

I think this will impress you: Capybaras are much more intelligent than most people realise. The ability to conceptualise is a mark of high intelligence. Not every human can conceptualise. However Tuff’n can! Tuff’n works out, in his mind, how to get the ring, which is stuck around his tummy, off.カピバラは、人々が知っているよりもはるかにインテリジェントです。タフンが彼の問題を解決するのを見てください。 水豚比人們知道的要聰明得多。看塔夫解決他的問題 水豚比人們知道的要聰明得多。看塔夫解決他的問題。

If you get a pet capybara and decide you cannot keep him/her, contact Janice Wolf at Rocky Ridge Refuge in northern Arkansas who has an Animal Sanctuary and has capybaras she has rescued.

I have never met a pet capybara, who is bonded with a human, who is happy. Capybaras bond so intensely, and are so emotionally sensitive, that they suffer greater separation anxiety than any other species, when that human leaves the home, or goes to work in a part of the house or garage to which they are denied access.

For this reason, if you truly care about animals and their welfare, and want to have capybaras in your life, you will ensure that the capybara is bonded with another capybara or animal that is always accessible to the capybara.

I have witnessed too much stress and anxiety in capybaras who are kept as pets and bonded with a human. It is heartbreaking to experience this.

wn-branfere-july-2012-murmel-tier

Also, you have to remember that capybaras are herd animals so if they are bonded with a human, that human becomes part of their herd. If a herd member disappears that means he/she is probably dead, eaten by a predator. This increases the pet capybaras anxiety exponentially.

Every person I know who lives with a pet capybara bonded to them has been bitten. The pet capybara views the human as part of the herd and treats them as they would any other herd member. Capybaras can be quite aggressive to each other, but since they have extra thick skin, their bites are not as harmful as when they bite a human, as humans have thinner skin.

You will also need to be a person with discipline. Once the excitement and novelty of living with a capybara wears off, you must be the sort of person who has the discipline to do the work necessary to ensure the health and emotional well-being of a capybara. Some pet capybara “owners” are happy to pay for expensive vet treatment, but may not have the discipline to do things that require time or hard work.

It is essential that your capybara has access to grass. If your garden does not have enough grass you must be prepared to lay down grass that will grow year round and ensure that the lawn is kept in good condition by scarifying and aerating it every winter.  A less satisfactory alternative is to provide fresh vegetables as a major part of the daily diet.

In their natural habitat a capybara’s diet is made up of 100% fresh vegetation. Of this 70% is grasses. Capybaras spend 45% of the day grazing in the dry season and 31% of the day grazing in the wet season. Grazing is a natural capybara activity, so quite apart from the nutritional benefits, it is very important for your capybara to be able to “graze” whenever they want to.

I have spent many years in close/intimate contact with both pet capybaras and capybaras who live as part of a herd with other capybaras.

I Believe that very, very few people would be able to provide the conditions necessary for their capybara to be happy as a pet.

Keeping a capybara as a pet, is nothing like having a pet cat or dog.   Cats and dogs have been domesticated over possibly as long as 35,000 years and have evolved so that they can coexist with humans and still have their emotional and physical needs met.   This is not the case with capybaras, who have evolved over 30 million years to be herd animals and to understand the communications and behaviour they encounter in the wild and from other capybaras.

Levels of the stress hormone cortisol are much higher in some wild animal species kept as pets and bonded with humans than in these species when they are bonded with other members of their own species. From my observations I suspect the same is true with capybaras.

Capybaras are intensely social, herd animals. They are very complex and sophisticated emotionally. They are also highly intelligent, at least as intelligent as the most intelligent dogs.

As herd animals they need a constant companion. If  a capybara’s primary bond is with a human and he becomes separated from that human, the separation anxiety the capybara experiences is far more intense than that of a dog. For this reason if  you care about the capybara’s happiness you must be prepared to be with him/her day and night. Not many people have the time and commitment needed to have a pet capybara.

There is a great deal of misinformation and inaccurate information about capybaras on the Internet.

Our video: Even the Most Sweet Natured Capybara Can Turn Aggressive 甘い性格のペットカピバラは攻撃的になる

Two very important aspects of rodent behaviour have come out of research and from my observations these apply equally to capybaras. Firstly, capybaras NEED to be in control of their lives. This makes them quite different from dogs who will adapt their behaviour to please you. Not many people want a pet that very often will not do what you want him to do.

If you are a control freak do not even think of having a capybara. Capybaras are NOT like dogs, who can be trained to behave in an appropriate way so that they can fit into your family and lifestyle. If you try to train and control a capybara, or indeed any rodent, you will only increase the stress level and anxiety of your captive pet.  Capybaras are very sensitive emotionally and they know when they are being controlled. If you expect to be able to control your pet capybara, your failure to do so, will probably harm, or even destroy, the relationship between you and the capybara.

Secondly, marking their territory is an essential part of capybara behaviour. Leaving a trail of urine where ever they go is a normal social courtesy. Their urine is like a signature or business card. It contains chemical information that communicates an individual’s sex and social status and any health issues the capybara may be experiencing. A capybara’s urine also allows other capybaras to discern genetic relatedness, a process which may have evolved to avoid inbreeding.

Capybaras have not evolved to understand human behaviour. Watching pet capybaras interact with humans I often observe their frustration as they try to understand and make sense of the way their human behaves, and I believe this may be the reason why some capybaras become aggressive from time to time with no apparent warning. If the capybara was bonded with other capybaras he/she would understand their behaviour and not be under stress.

I believe that being bonded with a human is inherently stressful for a capybara.
Romeo is the most fantastic Capybara as anyone who has seen the videos of Romeo kissing his human will realise. But sometimes he becomes aggressive with no prior warning.  I believe that being bonded with a human, whose behaviour he often does not understand can be very stressful for a capybara,  Capybaras are wild animals and you never know how your actions might play out in the mind of a wild animal. It’s too easy to show how incredibly adorable capybaras are. I’ve seen a couple of blogs lately suggesting capybaras make great pets. This is absolute rubbish and very irresponsible. Capybaras need an immense amount of love, time and commitment. Very few people would be able to give this. Too many capybaras get rejected as they get bigger and older and end up in refuges or die prematurely.

No capybara should ever sleep alone at night. A capybara in the wild would have the herd around him at all times. Even subordinate males are tolerated by the alpha male, on the periphery of the herd, as they act as a lookout and emit alarm calls to warn the herd if any danger approaches. (Subordinate males emit more alarm calls than the alpha male or the female capybaras in a wild herd.   Although each subordinate male mates with a female on fewer occasions than the alpha male, the total number of matings of all the subordinate males put together, is greater than that of the alpha male.)

Baby capybaras are incredibly adorable but people should not be seduced into thinking that this makes them suitable as pets:

In the video below:  Four-year-old Butter loves being nibbled by two-month-old Ko, Zabon’s two-month-old baby boy. Adult capybaras particularly love to have their ears nibbled and the babies seem to know this. Butter looks absolutely blissful as she rolls over.

If you are going to keep a pet capybara his/her needs MUST come first. It is potentially cruel to force the capybara into situations that make it anxious or fearful, to satisfy your needs or ego at the expense of the capybara’s happiness.

Capybaras need sun.  There is at least one capybara who lived inside the home in an enclosure and did not get enough, if any, sun. His bones were in a poor condition and his vet believed he should be put down so that he wouldn’t suffer any more.

To live with a pet capybara, you need to be very intelligent, very sensitive emotionally, and you need to understand animals.

Capybara’s natural behaviour includes marking their territory.  This is mostly done with urine, occasionally with faeces.  Not many people can cope with an animal marking its territory in their home.   My friends have removed all the carpets to make cleaning up this urine and faeces easier.  To segregate these very loving herd animals and confine them to a small area of your  home is cruel.  It may also lead to aggressive behaviour as the capybara will be unhappy.

The secret of living with Capybaras is to be sensitive to their body language and vocalisations, they will tell you what they want.   Being sensitive to their needs is essential to creating the necessary bond that will encourage them to want to do what you want them to do.  And to prevent them becoming unhappy and aggressive.

My friends are very strict in adhering to an optimum diet that most closely approximates what a capybara would eat in the wild. This is essential for capybara health and for their teeth.   The capybara digestive system evolved over 30 million years to take advantage of a diet that was high in fibre and low in nutritional content.  (See my blog:  ” What Should I Feed My Pet Capybara?”

https://capybaraworld.wordpress.com/2013/02/11/what-should-i-feed-my-pet-capybara/

Romeo and Tuff’n eat grass, hay and guinea pig feed. The hay and Guinea pig feed are available 24/7.   There are two bales of an Orchard Hay and  Timothy Hay mix in the living room. Whenever the capybaras want to chew on something, or they feel hungry, they go to the hay (or guinea pig feed). This means they do not chew pillowcases, plastic, comforters or any other inappropriate items of furniture.

Romeo and Tuff’n are never fed junk food, candy or table scraps. Romeo can sit on my friend’s lap at the dinner table and he will show no interest whatsoever in the food my friend is eating. If just once my friends had given him a treat from their dinner table he would constantly expect this to happen again.

It is worth noting just how sensitive capybaras are to any change in their routine, or any stress. Their faeces become softer.  And their mood changes.

As is the case with the best informed animal trainers, my friend does not use food as a reward. As the Naval officer in charge of training dogs said to me:  “You should not introduce food into the training process as it creates problems”.  Voice is a much more effective reward and Romeo positively fills with pride when my friend says “Good Boy Romeo”.

Additionally, while it may be easier to get an animal to perform a certain act or trick if it is given food as a reward, unfortunately, the end result is that the capybara will only perform or comply with your request if there is a food treat as a reward. Romeo knows what my friend’s expectations are and he sometimes chooses to behave himself.   My friend’s approval is very important to him.   He is an exceptionally good and well behaved capybara. Another thing I like is that my friend doesn’t ask Romeo to do senseless tricks just for the sake of it. There are plenty of useful things for Romeo to learn without turning him into a circus act.

I mention only Romeo as Tuff’n automatically learns from Romeo what behaviour is expected and appropriate, and therefore seldom needs any lessons from my friend. There were a couple of occasions when Tuff’n wet the bed. These occurred after a long and very tiring day, and perhaps Tuff’n felt too tired to make the effort to go to the “potty room”. On the third occasion my friend picked Tuff’n up, put him on the damp spot, gently pushing his nose down, and said very firmly “No”. He then picked Tuff’n up and carried him to the potty pan. Romeo also gave him a little ‘nose to nose ‘ talk, rubbing noses with him.  Tuff’n never wet the bed again.

Capybaras are capable of learning a surprising number of words. In addition to food related words Romeo knows “inside” and “outside” and “in the house”.  He knows the words “tell me a secret” and “give me a kiss”. And many other words and phrases as well!

In this video,

My friend is playing with Romeo, giving him an outlet for the sparring and play fighting that young capybaras enjoy in the wild. Romeo loves it and it allows him to release any pent-up energy and adrenaline. Romeo knows that ‘Inside’ and ‘In  the house’  mean this is designated as my friend’s territory, where he is the boss Capybara, and where Romeo does not spar.   Outside Romeo can play the boss. My friend always lets Romeo win the sparring contests outside so that Romeo feels that he is a successful and important male capybara.

At 2.07 secs you can hear Romeo clicking his teeth. Capybaras do this as a warning signal. The intention is to avoid a fight by persuading your opponent to abandon his attack and run off.   In the wild relatively few fights break out; the dominant male capybara who is number one in the herd hierarchy will warn the subordinate male, who almost always runs away.

Capybaras are highly intelligent and emotionally very sophisticated and complex. Very few people have the understanding, sensitivity and intelligence to keep them as house pets in a happy, fulfilled and stress free state.

Having two capybaras who are bonded with each other rather than with a human would be much better, as a fellow capybara can supply all the emotional needs that most humans would be unable to meet. However there can sometimes be problems with this due to the hierarchal nature of capybara society. It is usually impossible to keep two male capybaras, even if they are neutered, as their inclination would be to compete for dominance, i.e. fight.

Even with two females there can be dominance problems leading to injuries. One of my friends has two female capybaras who live in a field. The dominant female is often aggressive towards “her friend” and on one occasion inflicted such a severe injury that the exotic vet had to attend to the wound. Several trips to the vet followed which do not come cheap.

Now that Tuff’n is bigger than Romeo he often challenges Romeo leading to frequent minor injuries. Initially Romeo would walk away and try to avoid getting into a fight, knowing that my friend did not want him to bite Tuff’n. Eventually he realised he had to defend himself but Tuff’n’s playful aggression puts Romeo under a lot of stress and may be one of the reasons Romeo becomes aggressive to those humans who are part of his herd.

When I first met Romeo and Tuff’n, it was obvious that Romeo knew he was expected to behave in a friendly manner towards Tuff’n and not be aggressive to him. Romeo seemed to tolerate Tuff’n rather than to like him. There was one amusing scenario out by the pool, where Romeo was sitting in a tub of hot water. Tuff’n seeing Romeo, jumped in the tub to be beside him. Romeo moved to the far side of the tub to get away from Tuff’n.   Tuff’n moved over to be next to Romeo, and Romeo jumped out of the tub!

You can see this behaviour in this video:

Early on in their relationship, Tuff’n realised he had far more in common with Romeo than with the two humans. In fact when Tuff’n arrived my friends heard vocalisations from Romeo that they had never heard before; Romeo and Tuff’n were speaking their own language, even though neither had spent any time with adult capybaras from whom they could have learnt it. Tuff’n started to follow Romeo everywhere, and of course he learnt from Romeo’s behaviour.  Tuff’n shows separation anxiety if he cannot see Romeo, or if they are too far apart.  At least Romeo is always nearby.   Romeo, however, is bonded with humans and his life is much more stressful.

On one occasion Tuff’n came to sit with me on the beanbag for his afternoon nap. When he realised that Romeo was not going to join us, and indeed that he had no idea where Romeo was, he started to panic. He ran as fast as his little legs would carry him in the direction of the bedroom at the far end of the house. As he jumped on the trunk to reach the bed he noticed a lump under the bed covers on the bed, and his relief was palpable as he smelt Romeo’s odour coming from the lump. He then nestled down next to the lump as close as he possibly could (he doesn’t like going under the covers).   You may notice that the “lump” moves very slightly away each time little Tuff’n snuggles up to him in this video:

Capybaras have very sharp teeth and nip each other constantly when playing. As capybaras have very thick skin this does not cause any harm, but to a human it would result in constant injury (not serious but painful). Capybaras also occasionally bite each other either in play or when being aggressive. Not many humans could cope with this.

It is essential to have an exotic veterinarian and one with capybara experience. If you do not have access to an appropriate exotic vet, are you willing to accept that the animal you love, may very likely die sooner than it should?

Another friend who has two capybaras who live outside in a hot climate, wrote this: “My husband does not think that capybaras make good exotic pets for beginners. People need to know that capybaras are a lifestyle, and not an accessory to their lifestyle. As you said, the owner needs to be sensitive to the animal’s needs.   Is the person willing to provide the amount of time that is needed to spend with a capybara, willingly?”

She continues: “My husband thinks that too many people are drawn in by the cute factor and aren’t prepared for the work.  There are a wide variety of things that contribute to happy, healthy capybaras and it is hard for busy people to provide them, especially people who have little or no experience with exotics. It’s pretty obvious that most ordinary pet owners don’t want to mentally make accommodations that their beloved furbaby isn’t human. They think that if they give the animal the things that the human desires, then the animal will be grateful and behave in a human fashion. When a dog bites, there is some shock that it would do such a thing.   So, then you take that mentality and bring an exotic animal into the scenario. An animal that doesn’t have hundreds of generations trying to please or get along with humans. Capybaras have significant needs too. If the human-animal partnership fails, it will definitely be the capybara that suffers. There is a bit of resentment from professional animals keepers, towards exotic pet owners, because of this unrealistic attitude that many pet owners have. Bad husbandry or bad expectations, lead to injuries or death and public backlash. I don’t know who said it first, but the saying goes that many people falsely believe that not treating animals like humans, is itself inhumane. Just as I wouldn’t expect humans to want to live like a squid, I think it’s unrealistic to assume that a different species will think we do things best.”

She continues:  “Exotic pet owners have to accommodate to the lifestyle of the animal. As I see it, the big key with general animal ownership – and this would hold true for domestics or exotics – is sensitivity/attentiveness to their subtle body language. With professionals this is usually easier, because a professional animal keeper will spend all day long with the animals – it’s their job. The professional will  pick up on little noises or postures which might indicate that the animal is stressed or needs something. Sadly, in my country at least (USA), many people are more self involved. They are also occupied by lots of distractions. Paying close attention to what their animal is saying, or thinking, or trying to convey may well be beyond the capability of most people.( I certainly believe it is.) Your average person will jump to the first assumption regarding its capybara pets needs and not have the intelligence, sensitivity or depth of understanding to go beyond this.”

It takes a great deal of time and commitment to ensure the happiness of a pet capybara.

How many people are prepared to put the happiness of their pet capybara before their own happiness? This means ensuring that there is always somebody at home to keep an eye on the capybara and make sure it doesn’t get into difficulties. One of the major causes of death with pet capybaras comes from dangers encountered in the house or yard/garden, such as unsecured equipment, furniture etc.  Just as important is being there in the home to provide emotional support for your pet capybara. As I have said before, a capybara in the wild would never be alone. You only have to hear the plaintive calls of a capybara suffering separation anxiety to never want your capybara to experience that.

I haven’t even mentioned:

1)  Exotic vet bills which can run into thousands of dollars.  Having a capybara neutered by an experienced exotic vet cost at least $600 in 2013. Other bills may be far higher if the capybara becomes ill.

2)  Emptying the potty pan many times a day; at least 10-12.

3)  Capybara are semi aquatic.  This means you must provide them with somewhere to swim.  Capybaras are so graceful and playful in a pool or large pond;  would you want to deny them this pleasure?   In the wild they would spend much of the day submerged in water.   See my blog:  “Pet Capybara Pool Size. What Size Pool Does My Capybara Need?”:

4)  I personally don’t think it’s fair to keep a capybara in a cold climate. Their native habitat is semi tropical. You only have to see how much livelier Romeo is when the temperature reaches 65°F, to appreciate the effect of a warmer temperature on a capybara. A surprising and unacceptable number of capybaras have suffered frostbite.

Are you prepared to give up social engagements, and never travel away from home to ensure the happiness of your pet? I think there are very few people who could make this commitment.

Why I Would NOT Want to Be A Cute Animal, Especially A Cute Capybara

If I Was a Capybara:

I would not want to be dressed in uncomfortable and demeaning clothes. Most animals, including capybaras, hate wearing clothes. Capybaras are so beautiful why would anyone want to cover any part of a capybara’s body.

I would not want to have to earn my keep in a Capybara Cafe. It is a basic tenet of Animal Welfare that animals in captivity must be allowed to express their natural behaviours. For a capybara this means living in a habitat with unlimited access to grazing and a large pond or pool and a natural habitat with access to sun. A famous capybara lived inside the house and, therefore, did not get the sun his bones needed and his bones degenerated. His vet advised that he be put down to avoid further suffering.

Nobody who understands animals would want to see a capybara in a cafe.

It causes me great unhappiness that most people are not at all interested in me, my relationships with other capybaras, my personality and character. They just like my cuteness and only want to see cute photos of nameless capybaras. They do not want to learn about my species and the typical behaviours of my species

Most people who pretend to like us only want to watch very short videos of capybaras behaving cutely or exhibiting attention grabbing behaviour. They do not want to see slightly longer videos which show the normal range of my behaviour, how I behave with other capybaras and my relationships with other capybaras. Most people who pretend to love animals seem to have a very short attention span. My normal behaviour includes stopping to think or listen before continuing to act. Even a few seconds of inaction, on my part, results in these people becoming bored. The last thing they want to watch is a video where they might learn something about me or about capybaras in general.

Capybaras do not like to wear clothes. Dressing a pet capybara causes stress and interferes with the bond between the capybara and the human, as the capybara cannot understand why the human is doing this to him

I would not want to live in a zoo where I was imprisoned in a small, concrete floored enclosure with no grass and a tiny tub of water into which I could barely fit. Even a cattle trough would not allow me to swim and play and exhibit my full range of aquatic behaviours, which I so enjoy doing.

In Japan many people find that petting us relieves their stress, even though endless petting often causes us great stress. Because we are so useful as a source of stress relief there are many, many tiny zoos in totally inappropriate places like shopping malls (there are even 2 lions living in a small enclosure in a shopping mall in Japan!), or right next to noisy, polluted main roads.

I had incontrovertible proof today, if proof was needed, that many people in a Facebook capybara group do not care about capybaras when someone in this group asked what capybaras taste like and the moderator of this group thought this question and the concept it brought to mind were perfectly acceptable! Nobody who loves an animal would ever want to know what they tasted like. The very thought of capybaras being eaten brings tears to the eyes of anyone who loves these exceptional animals. People who really love animals would no more consider it acceptable to discuss eating an animal they loved than the husband they loved (or wife).

I realise that most people do not understand animals and cannot see things from an animal’s perspective. Therefore they do not understand what I am saying here.

I wish everyone who claims to like capybaras really loved us and cared about our emotional and physical well-being.

There is a link between the promotion of animals as “cute” and the trade in wild animals. Animals do not benefit in either case. In both cases animals suffer. Most people who are drawn to animals because of their cuteness do not understand animals and have no interest in these animals as sentient beings, individuals with their own unique personalities whose lives are important to them and to the people who love them.
