Capybaras are increasingly kept as exotic pets, but their complex social, environmental, and dietary needs make them difficult to keep humanely and they are frequently surrendered or kept in inadequate conditions.
Capybaras have very specific welfare requirements that most private owners cannot meet. Their social nature means a solitary capybara experiences ongoing psychological distress. They need access to deep water pools daily for bathing and temperature regulation. Their gastrointestinal system requires constant access to grass and hay, and they practise coprophagy to fully digest nutrients. Indoor housing causes welfare problems from inadequate space, flooring unsuitable for their feet, and inability to graze. Most capybaras kept as pets are eventually surrendered to sanctuaries when owners discover how demanding their needs are. Specialist rescues report chronic cases of malnutrition, isolation stress, and skin problems from inadequate water access.
