Does anybody know of a cat food that is good for a 2 month old kitten and 15 month old cat? George will eat his Science Diet wet in the am and I mix their dry food for feeding during the day when I'm not home, but I can't get him to eat his own food at night. He'll go to "cover" it, and then run to her food dish when she's had enough and finish hers. I would like to get wet and dry food that is nutritious for both of them. I don't want Raven to get overweight from me mixing the kitten's and her own food.
