Ok. I'll start off with telling you my wife and I rent an apartment from 2 cats. Elvis, a black & white longhair, and Sunny, a "morris" lookalike. Yesterday my wife brushed Sunny outside. She then started to brush Elvis, but he freaked out. He now hisses and snarls at us and Sunny. Poor Sunny doesn't understand why his friend of 3+ years is attacking him. I guess I'm just wondering if Elvis is caught in some permanent pschosis or if he'll calm down. This is my first two cats, and we're on day two of this bizarre behavior. We are a little worried about leaving Elvis and Sunny together. Please help guys, sorry for the lengthy post. Thanx in advance.
