Mink farming involves keeping highly active semi-aquatic predators in small wire cages, causing severe welfare deprivation and stereotypic behaviour in virtually all individuals.
Mink are adapted to patrol territories of several square kilometres and access water for swimming. Cage confinement denies all natural behaviour including hunting, swimming and territorial ranging. Virtually all farmed mink develop stereotypies indicating chronic psychological distress. Scientific consensus supports that mink are unable to adapt to farming conditions.
