Capybaras are the world's largest rodents, farmed in South America, increasingly popular as exotic pets, and facing habitat pressure in the wild. Their welfare across these contexts varies considerably.
Capybara kept as exotic pets face severe welfare challenges. They are highly social, water-dependent animals that require companionship of their own species and daily access to water deep enough to swim in. Most exotic pet environments cannot meet these needs. Singly-kept capybaras develop chronic stress. Without swimming access, skin problems develop. Their large size makes housing difficult and expensive. Farmed capybaras in Venezuela are managed in large outdoor ranch systems with water access — welfare conditions that are significantly better than typical exotic pet conditions, though harvest involves stressful roundup and slaughter. Urban capybara populations in South America face vehicle strike, dog attacks, and disease exposure.
