I have two cats. They were litter mates and I have had them since they were about 6 weeks old. I had a roommate when I got them and everything was great, but for the past two years it has been just me and the cats. I now have a boyfriend and one of my cats, Smokey (female, spayed), is very jealous of him and is very mean to him when he is here! He will try to be nice and pet her and play with him, but she just hisses and growls at him. At night, she will go on his side of the bed and scratch at the bed or make whatever noises she can to keep him awake, but she never disturbs me! My other cat, Oreo (female, spayed), seems to adore him. How can I get Smokey to at least be "civil" to my boyfriend?? I really think she may chase him away if she does not stop being so mean to him!
