- •
We examine long-term effects of preferred enrichment in American mink.
- •
Enrichment reduced stereotypic behaviour and glucocorticoids.
- •
Enriched mink showed signs of improved immunity and reduced developmental stress.
- •
Within the same housing type, stereotypic behaviour and welfare did not covary.
- •
Subtypes of stereotypic behaviour differ in sensitivity to current housing.
