Kevin didn't used to really live anywhere, he kinda lived in a few different places. Back a few years ago, there was the idea that he had a ice castle, but nowadays with his huge power limit debuff that is no longer possiable, or at least not easy. For a very long time he just lived with Fluffeh( the white & blue striped cat), so he was kinda homeless. I think I had the idea of him living in a cave somewhere, so I'm sticking with that.
