Pretty, fuzzy kitten. My Grey/Blue cat is a Moggie so I am not very familiar with grey breeds. There is a thread for Blue cat pictures. It is called post pictures of Blue/Gray/Maltese cats.

Nice kitten. It would be useful to see more pics. For example, to see the tail - if the tail is bushy, he is a medium hair for real. If the tail is narrow, its mostly a kitten fuzziness.
