Mink are semi-aquatic carnivores with complex behavioral needs that cannot be met in the wire battery cages used in fur farming.
Farmed mink confined to tiny wire cages without water access develop severe stereotypic behaviors including repetitive circling, head swaying, and self-mutilation. Their frustration at inability to express natural semi-aquatic behaviors causes chronic psychological distress. The wire floors cause foot injuries. Gassing with carbon dioxide or monoxide causes distress before unconsciousness.
