My buddy just now explored his cool side hide after being home for a week and a half. While I have moss in the warm side, which I dampen each day as it dries, I hadn't put any moss in the cool side since he's holed up on the warm side since I got him. So all things considered, should I put some dry moss in his cool side hide to tighten up the space? Or should I leave it be and assume part of the attraction is that it is less crowded?
