My boys get dry food only. I used to free feed them but Sky and Cirrus are little piggies and would eat all the food. They were also gaining too much weight. Now they're fed 2 times a day and receive 1/2 cup total each day. Cirrus is on Hills Prescription c/d diet because he had crystals and the other 3 eat a mixture of Max Cat Lite and Nutro Complete Care Weight Management Formula.
