Hi, I currently have a 2 yr old female spayed cat (Izzy). I adopted her from a shelter over a year ago and I don't think she was socialized with the other cats because she had health problems and was kept in a seperate room. When she finally got better I took her home. She is currently living at my home away from college (looking to move so I can bring her here!!) and dwells with my 11yr old female cat. I introduced them not as slow as I should have, but tried to keep them in seperate rooms. Of course they had tiffs and stuff and rarely do now. The problem IS that Izzy alot of the time wants to 'play' with the other cat but the other cat is much older and doesn't care, or sometimes takes offense. We have an outside cat, but he's so mellow and isn't very active, I've noticed that she has become more 'adrift' and I wonder if she needs a playmate. So, I'm asking for advice as how to know if your cat would benefit from another one?
