Two of my kittens (now six months) went to a home that has a dog. This dog is fine with the kittens, and she sleeps with them and grooms them. However, the owner just adopted a former fighting pit bull stray. A local rescue organization is going to get him trained and neutered for her, but I am still really worried about the kittens. She hasn't let the kittens around the dog and says she won't until he's trained and such... but is it even possible to train a former fighting dog to be nice to cats, especially when the dog used to kill neighborhood cats? He's still under a year old. Anyone have any experience with this kind of thing?
