Mink farming causes serious welfare harms rooted in the fundamental incompatibility between the species' biology and cage confinement on fur farms.
Mink are solitary, active predators that in nature travel several kilometres daily, hunt fish and aquatic prey, and maintain exclusive territories. Cage farming denies all of these natural behaviours. The result is near-universal stereotypy — repetitive pacing and circling — indicating chronic psychological suffering. The welfare case against mink farming is now considered scientifically established, and bans are spreading across Europe.
