Wolverines are wide-ranging carnivores whose welfare in zoo settings is challenged by their enormous natural territory requirements and secretive, solitary temperament.
Wolverine welfare in captivity is limited by the fundamental mismatch between their natural ranging behavior and any enclosure that could realistically be provided. Even large wolverine exhibits represent a fraction of natural territory size, and the inability to travel naturally may underlie the stereotypic pacing commonly observed in captive wolverines. Welfare improvement strategies focus on maximizing behavioral opportunity within constraints: large enclosures with varied terrain, multiple burrow access points, snow or substrate for denning behavior, and food caching enrichment where keepers hide food in complex substrates requiring extensive searching. Solitary housing is mandatory in most situations — wolverines maintained in pairs outside breeding season show chronic aggression and injury. The welfare case for wolverine in captivity is challenging; in situ conservation of their vast wilderness habitat is more aligned with this species needs.
