Hi everyone, my name is Chris and I have a 4 month old female cat named Missy. I have had her since she was 5 weeks old. She is a sweet cat but very hyper. She hasn't shown any agressive tendencies until now and even now it seems more defensive than aggressive really. My girlfriend and I split up a couple of weeks after I got Missy for about 2 1/2 months. We are trying to work things out and when she brought her daughter over Missy hissed at her. She does not attack or swipe at her, just hiss. Sometimes she will even creep over to her like she is trying to get a good smell of her, and when Allison sees her, Missy hisses. I don't understand what Missy is doing at all. If she wanted Allison to keep her distance, why does she walk over to her and hiss? If anyone can help me figure out the problem I would appreciate it.
