The capybara is the world’s largest rodent, weighing between 35-66kg and standing up to 65cm tall at the withers. Their closest relatives are rock cavies and guinea pigs, and they are native to the South American savannahs. Often described as a giant, social guinea pig, capybaras naturally live in family groups of up to 20 members, although in the wild, these groups can sometimes number up to 100.
Because of their size and unique social needs, capybaras are generally seen more in zoos or wildlife centres than as household pets. However, they do appeal to those seeking an exotic pet from the larger rodent family.
In the UK, it is legal to own a capybara, but you must obtain a licence issued by your local council. This licence ensures that your home, garden, and facilities are suitable for the animal’s welfare and that your neighbours or local community will not be negatively impacted. Licensing takes into account the capybara’s space requirements, need for water access, and security to prevent escape or nuisance.
It’s important to note that capybaras are wild animals with specific care needs that differ greatly from typical domesticated pets. Meeting these needs is essential for ethical ownership and animal welfare.
Capybaras are not cheap pets. The acquisition itself can cost several thousand pounds, reflecting their rarity. Beyond purchase, care costs add up significantly. You’ll need to invest in specialised enclosures, fencing, a swimming pool, appropriate food, regular veterinary care, bedding, and possibly heating or UV lighting in colder months.
These ongoing expenses, combined with the initial investment, mean capybaras are a commitment best considered by experienced keepers with adequate resources and space.
Capybaras grow to over four feet long, so ample space is vital. A minimum outdoor enclosure of 20ft square is recommended for one to three capybaras, with distinct sunny and shaded areas to allow them to regulate their body temperature.
Secure fencing at least four feet high and set in concrete is crucial, as capybaras are adept at squeezing through small gaps. Additionally, indoor kennelling should be available to provide shelter from cold weather, with suitable bedding like hay. Providing a heat lamp during colder months helps keep them comfortable.
Access to clean, fresh water at all times is essential, alongside provision of a swimming hole to mimic their natural habitat. The pool should have gently sloping ramp access, a minimum depth of 3.5 feet to allow full submersion, and be wide enough to accommodate their swimming needs.
Capybaras are herbivores, grazing mainly on grasses and aquatic plants. They also enjoy fresh fruit and vegetables as treats. They can naturally keep a large lawn trimmed by grazing, making them both pets and natural lawnmowers.
Hay and cattle pellets should be part of their regular diet, and you should avoid using pesticides or herbicides on the grasses they access. Capybaras’ teeth grow continuously, so providing safe branches such as willow or birch encourages natural chewing and helps prevent dental problems. Always verify the safety of wood before offering it.
Owning a capybara is a complex undertaking. They require social companionship, appropriate space, specialised facilities, and daily care that goes beyond typical domestic pets. If you cannot meet these requirements, capybaras are not the right pets for you.
Before acquiring any exotic animal, always consider the ethical implications and whether you can provide the environment and care necessary for the animal’s well-being. Where possible, visiting sanctuaries or wildlife centres to observe and support capybaras is a more responsible choice to appreciate these fascinating creatures.
