Mink farming is banned in many countries due to serious welfare concerns about highly territorial animals in cages.
Mink are semi-aquatic carnivores with strong motivations for swimming, burrowing, and maintaining large territories. Cage farming denies all of these fundamental behavioural drives. The high prevalence of stereotypies — circling, head-weaving, and self-mutilation — documents the chronic psychological suffering of caged mink. The evidence for welfare harm in mink farming is among the strongest for any farmed species.
