Sloths have remarkably specific habitat and dietary requirements. Their welfare in captivity is challenging due to the difficulty of replicating their arboreal, highly specialised ecology.
Sloth welfare in captivity presents extreme challenges because their highly specialised ecology — including dietary specialisation, extreme metabolic rate, and sensitivity to stress — makes adequate provision genuinely difficult. Three-toed sloths have historically had poor captive survival rates due to the difficulty of replicating their specialised leaf diet and sensitivity to dietary changes. The apparent passivity of sloths is misleading — they are not indifferent to their environment but are physiologically constrained, and stress responses in these animals may be less visible but equally real. Wild sloth tourism, where tourists hold and photograph sloths for social media, causes serious welfare harm through stress, inappropriate temperature changes, and disruption of feeding and rest behaviour.
