If Boss Man softens a bit...maybe you could keep the kitty in a large dog cage in your bedroom, away from Felix for a bit. After he's neutered, of course!
If I could provide the cat a furever home I would have,its not so much the "boss man"(said joking)thats the problem there are other factors that come in to play.I would never be able to cage an animal even if it were short term.He deserves better than that.This is kinda out of my hands now.Like I said,the cat is now with humane services,in hopes for an adoption to a loving,furever home.
