I was gifted a kit to try couple years ago, I had my own family if ferrets in a big run, an kept this kit in a hutch for first few weeks, letting her sniff them through wire, they hated her. I had 3 daughters, 2 sons and mum. Kept trying them together, tried everything an EVERY TIME they could get to her they tried to kill her, they even worked as a team lol in end I gave her to mate I ferret with, even his ferrets were iffy with her, but tolerate her. A whole year passes by and we out ferreting, I drop in mum and daughter, mate drops in the outsider lol and they attack her In warren, totally
