He finally figured out he can lay UNDER it instead of laying diagonally across it with his nose touching either the glass or the floor. I re-arranged his enclosure a bit to make more room for him to move about, and I think he likes it better now. Jabba will lay in a circle as he hides under his log now with just either the tip of his nose or the tip of his tail hanging out.
Tonight he's sleeping under it. Looks like he took a midnight snack in there with him too. :lol:
