Capybaras — the world's largest rodents — are increasingly kept as exotic pets. Their complex social and environmental needs make private ownership almost always inadequate.
Social media popularity of capybaras has driven a surge in exotic pet ownership that creates significant animal welfare problems. Most owners cannot provide the deep water access, large outdoor space, appropriate social groupings, and specialist veterinary care that capybaras require. Single capybaras experience chronic stress from social isolation. Inadequate water access causes skin and respiratory problems. The stress of domestic environments causes immune suppression and behavioral problems that owners interpret as personality rather than welfare signals. Capybaras belong in large, semi-aquatic social settings — not domestic living rooms.
