Mink farming for fur confines highly active, semi-aquatic carnivores in wire cages, causing severe welfare problems. COVID-19 outbreaks accelerated bans but millions of mink are still farmed globally.
Mink are among the species least suited to intensive farm conditions. As solitary, wide-ranging predators with strong swimming drives, they are profoundly frustrated by wire cage confinement without water access. The high prevalence of stereotypic behaviour is one of the clearest welfare indicators available, representing a chronic failure to meet motivational needs. Self-directed aggression, infanticide, and high kit mortality rates further indicate severe welfare compromise. Unlike some farm animal welfare problems where incremental improvements are possible within existing systems, mink welfare researchers largely conclude that no commercially viable housing system can adequately meet mink behavioural needs. Phase-out is the welfare-consistent outcome.
