I just got a new cat, a Blue Point Himilayan female. I already had a red Persian, who is the most gentle boy ever. We have begun our socialization process but there has been some hissing going on. I've only let the cats be in the same room for short periods of time and just when I'm present. So far we have not had any fighting. Last night the new kitty came by me on the couch and I petted her a little bit but then later when she was down on the floor I reached toward her and she hissed, batted and even growled at me. I'm not able to pick her up so I have to lure her back to her room with treats when I let her out of her room. My golden boy seems to be afraid of her...he just cowers back in a corner and stares. Any suggestions?
