Sloths are highly specialised arboreal animals with unique metabolic and behavioural requirements that make their welfare in captivity challenging to achieve.
Sloth welfare in captivity requires understanding and accommodating their extreme metabolic adaptations. Their very low metabolic rate means they are highly sensitive to temperature changes and stress responses are slower and less obvious than in other species. Dietary management is critical because their specialised leaf-fermenting digestion cannot process most conventional zoo animal foods safely. Solitary management with large arboreal space is essential. The popularity of sloths in wildlife tourism and as ambassador animals creates significant welfare pressure from inappropriate handling and public contact. Sloths showing slow movement and apparent contentment may actually be showing stress responses easily mistaken for their normal low-activity state.
