Capybaras are highly social, semi-aquatic rodents from South America. Their welfare in zoos depends on maintaining appropriate social groups, water access, and tropical environmental conditions.
Capybara welfare in zoos is generally more achievable than for many species because they adapt well to group living in enclosed spaces when managed appropriately. The key welfare requirements are: adequate pool access for at least daily swimming and cooling, appropriate group sizes of at least 4-6 individuals to allow natural social dynamics, tropical temperature management to prevent cold stress, and ad libitum grass and hay to support dental health and gut function. Social management is important — capybaras establish clear hierarchies and chronic disruption through individual removals and additions causes stress. Welfare assessment can track time spent in water, social interaction rates, and gnawing behaviour as indicators of overall welfare quality.
