Ours is overweight, but slightly less so than when we adopted her. We feed her on a small helping of canned food, and a small helping of dried food, twice a day. We would feed her all wet food, but without some dried food to crunch her teeth fur up.

She appears a bit stiff in the front legs when going downstairs, which is why we're trying to slim her down. As most people find, cats don't take kindly to being fed less than they would like - she makes a noise like a rusty hinge.
