tughcookie, other than checking for worms, I believe that I'd check his diet. I do have a cat that gasses up real easy, namely Fawn. I had to quit feeding Tiger the large bulk cat food that is normally purchased from the feed store, because she would barf it up. The only thing that can be seen from this, otherwise excellent food, is that it might swell up in their tummy after it has been in there for an hour or so. A cat normally does not hold food in their system for long becuase, in their natural-wild state, they do not know when or where their next meal is going to come from. What are you feeding him for kitten food? I'd start with that.
