Mountain lions in zoo collections require large, complex territories that challenge many facilities — evidence-based space and enrichment standards are improving welfare outcomes.
Mountain lion welfare in captivity is constrained by the species' large natural territory requirements and solitary behavior — characteristics that make high-welfare captive management resource-intensive. Facilities that house mountain lions in small exhibits with limited complexity fail to meet the behavioral needs of an animal evolved for wide-ranging, solitary predation. Best-practice institutions provide exhibits exceeding minimum recommendations, with elevated platforms, varied substrates, climbing structures, and regular enrichment that enables prey-related behaviors. Facilities without resources for adequate mountain lion welfare should consider whether the species belongs in their collection or whether individuals should be transferred to better-resourced institutions. The welfare argument for high standards is unambiguous: chronically stressed mountain lions experience measurably poorer welfare regardless of their physical health.
