Cat was eating so much volume she was vomiting. Weight control food doesn't help with this issue. Additionally, my obese cat was on a very controlled amount of "diet" food for years, it doesn't actually work. Switched him to Blue Buffalo and didn't observe any weight change. And before anyone asks, yes, the cat has been to the vet and has gotten all the blood work and I've tried multiple meals and everything. Don't even go there.
