Hello. My cat has a a weight problem. We adopted her from a shelter I'd say about a year and a half ago. When we first got her, I expected her to gain a little weight but she has continued to gain weight with no signs of stopping and now she is up to 18 pounds. Not only that, but she sleeps more- has less interest in playing, and more interest in food. She used to be a pretty well behaved cat, and now everytime I leave any kind of food out of her interest, she tries to get at it one way or another. I don't feed her scraps or give in to her begging. I don't know what to do. She is an indoor cat.
I am considering putting her on diet cat food, the only problem is we have another cat who is at a good weight- and I don't want him to lose weight. Will this effect him?
I've bought her plenty of cat toys, which she will play with occasionally- our other cat won't play with her, and usually hisses at her when she tries (nice huh?). I'm reluctant to let her outside, as my last cat got outside and I haven't seen her since. Any ideas?
