I just love that ferret.
I used to have 3 but hubby wouldn't let me keep the ferrets when I wanted to keep fish so I gave them to one of hubbys friends.
I had one female who looked very much like weasle and I called her Avenger (as in masked avenger)
I had a male called Houdini as he had almost escaped from his box by the time I had got him home. Houdini was castrated when I got him.
I also adopted a stray ferret that was found around our street, some kids found it and knew that I had some and asked if I would take it. Didn't see any harm in it, if I had advertised that it had been found it would have been very difficult for anyone to prove that it was rightfully theirs so i kept it.
Avenger was mated once when I had her, she had six babies but they were all too small and died.
Since giving her away she has been mated again and she has had another 6 babies all of which have survived.
She was a good mum just that the babies were too small, her first litter.
Anyway I have to agree POTM for weasle.
Sorry to hear about your cat
