Lions, tigers, leopards, and other big cats in zoos require specialized welfare management of their territorial instincts, space needs, and hunting drives - with wide variation in how well facilities meet these needs.
Big cats in inadequate zoo facilities show clear welfare deficits - the stereotypic pacing observed in poorly managed big cat exhibits is a direct behavioral indicator of chronic stress and behavioral deprivation. Tigers pacing their exhibit circuits dozens of times per hour, lions spending 20+ hours per day inactive in undersized enclosures - these behaviors reflect the gap between what these animals are and what their environments allow. Well-managed facilities with large naturalistic enclosures, complex environmental design, and extensive enrichment programs demonstrably reduce stereotypies and improve behavioral diversity. The elimination of big cat private ownership through the Big Cat Public Safety Act was a genuine welfare improvement, but standards in accredited facilities themselves vary significantly.
