Update: Today was my day off so we drove a little further out south to visit a store I've never been to and bought a medium rat. I already had newspaper in his cage so I threw the rat in and once again he hit like a freight train. As soon as it went limp he began munching. I think it's safe to say this is what he needed ^^
