Wolverines are wide-ranging, high-energy carnivores whose welfare in captivity requires large spaces, complex environments and intensive enrichment programmes.
Wolverine welfare in captivity is fundamentally constrained by the impossibility of replicating their vast natural ranges. Well-designed facilities compensate through large, topographically varied enclosures, intensive daily enrichment, access to natural substrates year-round, and management that respects their solitary nature. Forced proximity to other wolverines causes chronic stress. Enrichment must be changed frequently to prevent habituation — wolverines are intelligent enough to lose interest rapidly in predictable stimuli. Regular welfare assessment using validated behavioural indicators guides enclosure improvements and ensures care quality over the animal's lifespan.
