CNN PRODUCER NOTE Tattoo10 says the vet has told her Tattoo needs to lose weight, or he could develop diabetes and other health problems. The cat should probably weigh 12 pounds, but he's gotten up to more than 22 pounds -- so heavy that it's difficult to pick him up, and he has trouble moving around. She is concerned about his condition. 'We have tried to control his portions by giving him half a portion in the mornings and then removing the dish until the evening. It becomes difficult because we have another older cat who eats smaller meals several times a day. Tattoo keeps her away from the food dish or eats what I she leaves over.' She wonders if the food he eats -- a combination of wet and dry -- has ingredients that pets can get addicted to.
