Large cats in zoos require significant territory, complexity, and behavioral opportunities to maintain good welfare. Meeting their spatial and cognitive needs remains one of zoo keeping's most challenging welfare problems.
Large cat welfare in zoos represents one of the field's most difficult challenges because the gap between what felids need and what any zoo can realistically provide is large. A lion's ranging behavior, territorial patrolling, and hunting sequences simply cannot be replicated in captivity. What welfare-focused zoos can do is minimize the gap: provide as much space as possible, maximize complexity within that space, offer cognitively demanding feeding enrichment that engages hunting instincts, and monitor pacing and other stereotypies as welfare indicators. The increasing willingness of accredited zoos to retire felid exhibits that cannot meet modern welfare standards, rather than continuing to keep cats in inadequate conditions, reflects genuine moral progress in zoo keeping.
