Mink farming keeps semi-aquatic, wide-ranging predators in small wire cages for their entire lives to produce fur. The welfare case against mink farming is among the strongest in animal agriculture, and bans are spreading across Europe.
Mink farming welfare is one of the clearest cases in animal agriculture. The extreme mismatch between the natural behavioural needs of minks — wide-ranging, swimming, solitary predators — and the conditions of intensive cage farming produces among the highest rates of stereotypic behaviour documented for any species. These stereotypies are indicators of severe and chronic psychological suffering. Minks show high levels of fear responses to humans and conspecifics in cage conditions. The brief period of enrichment provision mandated in some countries (objects in cage, swimming water access) reduces but does not eliminate these welfare problems because the fundamental constraint — a small cage — cannot be overcome. The welfare case for mink farming bans is compelling and has been accepted by the UK, several EU member states, and others.
