I think some people assume that if an animal will attack an animal product, something has gone wrong in the treatment/tanning / preserving. I'm not convinced. Though years ago we had a coincidence of one particular cat and a pair of fluffy slippers my mother owned at the time (we think they must have been rabbit fur).....
His adoptive brother was never bothered by them, though, so.
My current cat has taken to occasionally peeing on one of my coats to indicate displeasure. I'd rather she bit me.
Yeah, that's what I had in mind, interesting to hear about that coincidence
