The scientific evidence on mink welfare in farming systems informed legislation banning mink farming in multiple countries. Understanding this evidence clarifies what welfare science can achieve.
Mink welfare science demonstrates how systematic research can inform policy with genuine welfare impact. The evidence accumulated over decades showed clearly that mink in standard farming environments exhibit chronic behavioral frustration at rates far exceeding other farmed species. Stereotypic pacing - the most visible indicator - appears because the mink's behavioral system generates movement patterns that have nowhere productive to go in a small cage. Water access, ranging behavior, and complex foraging drives are simply incompatible with commercial cage farming economics. The policy response - banning mink farming in multiple European countries - represents one of the few cases where welfare science directly produced categorical welfare improvement through legislative change.
