I have my first cat, more like the cat has me... I am feeding Blue Buffalo indoor dry cat food. I would like to mix the dry and the wet food. My cat is 8.8 pounds. The dry food bag says to feed from 1/4 to 1/2 cup per day. If I were to do a mix how much wet food should I give and how much dry. I do not want to overfeed because he is an indoor cat. Any food information you can provide would be great!!!!!
