Has your vet suggested a light or weight reducing food? How much food are you feeding per day? Are you free-feeding? Does the cat get any treats or people food?

Sorry for all the questions, just wanting to help out if I can. My mom currently has an obese cat and I'm working with her to get her cat's weight down before she ends up with a diabetic cat.
