I have a cat who is now barely a kitten, he is almost 8 months old and in the last week he has started puking, a lot and often. He also moans, and makes little noises indicating that he may be in pain and I am pretty sure this is there slim time, especially for a male but he is really skinny. I see him eating all the time so I know whatever is not affecting his appetite, but I dont have money to take him to the vet right at the moment so I was hoping for some insight, thanks in advanced!

It could be anything from a hairball, worms, or infection. While eating, drinking and using the bathroom is a good sign. If you allow this to goo on for to long it will cause him serious problems , maybe even death. When he throws up dig through it and see what you find. It could be as simple as a hairball and when he gets it all up he will stop throwing up. If that is the case you will need to brush him often, get him on a hairball treatment, or feed him hairball formula food.
