I have had my cat Bat for 1 1/2 years now and recently my cousin found a kitten in the road and almost hit her with his car, so he naturally brought her to the cat lover of the family. Me. I've had her for probably about 2 months now. (Her name's Itty Bitty Kitty by the way.) At first Bat didn't like her, and after a couple days he warmed up to her, which I knew was natural. They slept together and got along perfectly fine. Now suddenly every time she gets near him he hisses at her and smacks her in the face until she runs away. What happened? Any ideas? Thanks!
