I just adopted a beautiful black and white female cat from a rescue organazation. She seems to be very healthy and I have all her old vet records as well stating that she is fine. But she weighs 20 lbs and the people at the adoption place did not seem concerned by this, and did not give me a special diet or anything for her. I love my new girl I just worry that she could develop problems later on from being overweight. I was just wondering what kind of cat food I should be giving her. I bought a cat food formulated for indoor cats that suppose to help keep the cat lean but I didn't know if I needed that or some other weight control cat food.
