Sloths have unique metabolic and behavioral adaptations that create specific welfare challenges in captivity. Their care requires specialized knowledge often absent in general zoo settings.
Sloth welfare is a particularly challenging area because their unusual physiology and behavioral subtlety make welfare assessment difficult, and because their appealing appearance has driven inappropriate captive use in selfie tourism and wildlife encounters. Three-toed sloths have such specialized dietary requirements that captive maintenance invariably involves significant welfare compromise — most captive three-toed sloths die within weeks to months of capture. Two-toed sloths are more adaptable but still require specialized diet, appropriate temperatures, and behavioral complexity including hanging opportunities, varied substrate, and nocturnal feeding schedules that match their natural activity patterns. The sloth selfie industry — where sloths are handled repeatedly by tourists for photographs — causes significant stress that their stoic behavioral repertoire conceals from naive observers.
