Wild American mink escaped from fur farms have established feral populations causing wildlife damage while farmed mink face severe welfare challenges.
Farmed mink welfare is among the most severely compromised in commercial animal agriculture. Wire cage confinement prevents swimming, hunting, and the ranging behavior that mink are biologically motivated to perform. Stereotypic behaviors including repetitive circling indicate chronic frustration from behavioral deprivation. The mink's semi-aquatic nature makes water deprivation particularly significant. Fur farming bans across European countries reflect the impossibility of meeting mink welfare needs in commercial cage systems.
