My two kitties are about 10 mos. old and I feed them about 4 oz. of wet food each, split into two meals. They also get some dry kitten food, probably about 1/4 cup split up into two times. Once before I leave for work, right after their wet meal and the other before I go to bed. I'm just kind of winging it too, because it's been ages since I've had kitties. Hope I'm doing ok. I was told cats are considered "kittens" until 1 year old.
