We've been feeding our two 7mo kittens a mixture of Hill's Science Diet for healthy development and Friskies for their breakfast and dinner. Usually half and half of the recommended amount they apparently should be eating a day by the vet's suggestion. Obviously, they prefer the wet food way more, but even feeding them the recommended amount, the brother especially, has been gaining a lot of weight. Again, 7mo, and he's already 12lbs, and the sister about 8. They're tabbys so I believe they're going to be big, but they're just growing so fast. When we first got them back in September, the brother was 8, and the sister was 5lbs. I'm wondering if increasing or lessening either one of the foods will help, or maybe they're just supposed to be this big, not quite sure. Thanks for any input.
