Truthfully, I don't want/need another cat, but, having said that, I wouldn't do anything negative, either.
I know that feeling!! I now have 5 ferrets. I didn't need or want a fifth ferret...BUT...there was this poor little girl all by herself in a cage at the petstore with 3 big signs plastered to het cage that said DO NOT TOUCH!! BITES!! I tried to give some helpful suggestions of why she bit...she was all by herself and not with the other fuzzy, they weren't giving her moistened food(she was probably hungry and being just a baby couldn't chew the hard kibble well) The store didn't want to listen to me. I heard from another employee that they were going to send her back. I know the company they got her from. She would have been PTS. I argued with the store..called that company who said they would allow her to go to a shelter rather than take her back. Argued some more with the store....they lied to me..they said they wouldn't send her back to be PTS, that they'd keep her until she sold...but I'm so sure she would have sold with BITES!! written across the cage. I finally talked them out of her. I think they just wanted to shut me up.

So now I have 5. I wasn't sure what I would do with her because I really didn't need another...but its so hard to find someone who's ferret knowledgeable...sooooo I have 5 fuzzies. I'm such a sucker.
