Wolverines are solitary, wide-ranging carnivores rarely kept in zoos. Meeting their exceptional space and behavioral needs in captivity requires specialized facilities and management.
Wolverine welfare in zoo settings is particularly challenging because the gap between what captivity can provide and what wolverines need is especially large. Their extraordinary territorial requirements mean even the most generous zoo enclosure represents a tiny fraction of natural territory. Solitary housing is welfare-appropriate given their territoriality, but preventing all conspecific contact removes any opportunity for species-appropriate social interaction. Enclosures must provide opportunities for caching food — hiding items and returning to retrieve them is a strong behavioral drive. Climbing structures, varied substrates, burrowing opportunities, and scent-marking areas support behavioral expression. Wolverines are most active at dawn and dusk and in cold conditions; thermal management and activity-aligned public viewing hours matter for welfare. Their rarity in captivity means husbandry knowledge is limited — facilities keeping wolverines should participate in international knowledge-sharing networks.
