I found a kitten over the weekend at work, he is in pretty good shape for the most part but he seems very thin to me, and at first I did have some trouble getting him to eat solid food so far he's only been able to eat dry food mixed with canned and warm water so it's pretty much just mush he can lick up. I've been told he's about 6-8 weeks. My questions are is he thin? If so, how often should I be feeding him and how much so that he gains the weight he needs in a healthy way? So far I've been feeding whenever he seems to be hungry but I don't want to give him too much.
