Private ownership of big cats — lions, tigers, leopards, cougars — is legal in many US states and other countries. The welfare implications of private big cat ownership are severe and the conservation justification negligible.
Private big cat ownership represents a near-perfect convergence of welfare failure and conservation irrelevance. The animals suffer profoundly: space requirements for big cats are measured in square miles of territory for wild counterparts; private facilities provide acres at best, often far less. Social needs of these largely solitary-but-territorially-complex animals are incompatible with typical private keeping. Nutritional needs requiring whole prey or specialized formulations are frequently inadequately met. The conservation justification — that private breeding preserves tiger genetics — is false: most privately owned animals are generic or hybrid tigers outside studbook programs, contributing nothing to wild tiger conservation. The US Big Cat Public Safety Act was a significant reform, addressing the cub petting industry directly; full enforcement and international equivalents remain needed.
