Hi there my cat chirpers got spayed about 4 years ago.she was not skinny but in nice shape.,since she got spayed she plumped out like a balloon.She is 7 years old now and doesn't over eat.What can do to get her to loose weight?I feed her friskies and or meow mix traditional cats foods plus she gets a canned treat every day in a small amount.She is a munchkin breed with very short legs so normal weight for this breed of cat would probably be about 8-9lbs.she weighs about 12 as of right now.Shes pretty active for her age and gets to roam around while getting walked on a leash.Im very protective of our extended family so I wouldn't ever just let them roam freely.What can I do/
