Mountain lions are among the most space-intensive felids to keep in zoological settings, with their solitary nature, large home range requirements, and cryptic behavior creating distinctive welfare management challenges.
Mountain lion welfare in captivity is fundamentally constrained by the difficulty of providing environments that satisfy the locomotor and spatial needs of a wide-ranging solitary predator. Large enclosures with complex topography — elevated platforms, hiding spots, varied substrate, and scent-marking surfaces — are the minimum requirement for avoiding stereotypic pacing in this species. Visitor pressure to see active animals during daytime hours conflicts with the naturally crepuscular activity pattern of mountain lions, and exhibits that attempt to maximize visibility often do so at the expense of providing shelter and hiding opportunities that welfare requires. The solitary nature of mountain lions means that social enrichment from conspecifics is inappropriate and that human-animal relationships with experienced keepers may play a welfare-relevant role in their cognitive and social lives. Mountain lions in well-designed large enclosures with dedicated keeper relationships show behavioral repertoires and activity diversity indicative of better welfare than those in inadequate facilities.
