So I adopted my cat (Mitsy) when she was three months old at my local shelter and since then she has never had to live with any other animals. She is almost ten years old so she’s been the only one for quite some time. When I moved for college I brought her with me and I’ve several roommates over the years. She’s never taken too kindly to new people, isn’t social, and scares easily, she’s always been like this, nothing new. A few months ago I got a new roommate who also brought her cat with her, Floyd. Floyd is a two year old male, VERY sweet but very skittish and shy and Mitsy is not liking another cat in her space. He mostly stays in my roommates room and doesn’t come out much because he’s scared of her. She’ll go to him and start screaming, hissing, and swatting at him. Mitsy is declawed and is quite small so she does no physical harm and Floyd had claws and is much larger but he won’t use them or fight back. Anytime she even catches a glimpse of him she goes and starts a fight. She’ll even go into his room and eat his food and fight if he comes out from under the bed (which is where he flees when she comes near) I feel awful for Floyd and don’t want either cats feeling stressed or uncomfortable. I still have a few months with them and want peace for both cats. Floyd seems to want to get along and play but Misty is not having it. Any advice on how to help them coexist?
