Mink are semi-aquatic carnivores whose behavioral needs are fundamentally incompatible with standard fur farm cage conditions.
Mink are highly motivated to perform natural behaviors — swimming, hunting, exploring — that are largely impossible in barren wire mesh cages. The result is extreme frustration and chronic stress, evidenced by high rates of stereotypic behaviors, fur-chewing, and aggression. Scientific evidence consistently shows that mink welfare cannot be adequately provided in conventional cage systems regardless of enrichment attempts. Many jurisdictions now recognize this incompatibility in law.
