Three-toed and two-toed sloths have highly specific metabolic, thermal, and behavioral needs that make them challenging to house well in captivity, with welfare often compromised by misunderstanding.
Sloth welfare in captivity is frequently compromised by misunderstanding their biology. Their slow movements are not inactivity caused by stress — they are a metabolic adaptation that must be respected rather than disturbed. Touch experiences where visitors handle sloths are highly welfare-compromising: the physiological stress response in touched sloths is measurable and significant. Dietary management is challenging because sloths are dietary specialists with complex nutritional requirements. High-welfare sloth programs invest in appropriate diet research, hands-off management that minimizes human contact, and thermal environments matching their specific tropical forest needs.
