Capybaras are the world's largest rodents and increasingly popular in exotic pet markets, but their welfare needs are substantial and often poorly understood.
Capybaras need water access, social companions, and large spaces — needs that are rarely met in exotic pet contexts. A capybara kept alone in a garden without water access is experiencing chronic deprivation across multiple dimensions simultaneously. Their social needs are particularly acute: capybaras in wild groups maintain constant vocal and physical contact, and isolated individuals show clear behavioural distress. The emerging popularity of capybaras as pets on social media is driving demand in ways that welfare organisations regard with alarm.
