Re: Nasty cat
I don't blame you! I'd get irritated too if my cat has a poopy bum and wouldn't let me clean it!
Ok, for the diet. Since you already feed wet, you should stop allowing Jasmine to have ANY dry food at all. Nito eats about 5 oz of wet a day, give or take, and has dry snacks. This maintains his weight. If you cut her access to the dry food, it might really help. Dry food, especially grocery store brands like 9-lives are chock full of grains, which are carbs that cats have trouble processing, so they get turned right to fat. The 2/3 can of wet food (if it's a 5oz can) should be a good amount to help her lose weight, but you need to weigh her often to see if it's working (which might be impossible in your case!)
What kinds of toys have you tried? Have you ever tried Da-Bird- It's a feather toy that spins sort of like a fishing lure and makes a sound similar to birds flapping their wings and it can get even the most stubborn cats to play. You could also try laser pointers. Or be creative. My cat Lil'Fella needed to drop a few pounds, and he's a lazy boy whose definition of playing was laying on his back and swatting. So we'd take him to the backyard and drop him in the bunny pen, which he hates. He'd jump the fence and run all the way across our huge back yard to the house. Give him a couple laps of that, and he was all set for exercise for the day!
