Mink are semi-aquatic carnivores with strong behavioral needs that are fundamentally incompatible with typical fur farming conditions. The welfare case against mink farming has contributed to bans in over 20 countries.
Mink farming welfare problems are structural: no commercially viable modification to standard mink farming produces adequate welfare for an animal with such strong semi-aquatic and ranging behavioral needs. The stereotypic behaviors seen in essentially all farmed mink are not individual abnormalities but a species-level response to conditions that fundamentally frustrate evolved behavioral drives. Unlike many farm animal welfare issues where improvements are feasible within existing production systems, mink welfare experts consistently conclude that acceptable mink welfare is incompatible with commercial fur farming economics. This is why the welfare evidence has supported bans rather than certification-based improvement programs in jurisdiction after jurisdiction.
