Hello! I'm happy to have found this forum, and I would like some advice. I have a 4-1/2 year old cat who weighs 18 lbs. 12 oz. The vet would like him to lose a little weight. I was feeding him three times a day, a 3 oz. can of Fancy Feast each feeding. I'm trying to cut him down to 2 cans a day, but it's been a month and he's still acting like he's hungry. How much should he be fed daily?
