Its about to be 6 weeks since Lithir (western hognose) last ate.. I though for sure he would eat right after his shed (almost 2 weeks ago now), but he still hasn't.

His humidity is back to normal. I stopped misting as soon as he shed his skin. His temps are staying at around 85ish on the warm side, and he's been spending most of his time on the warm side as of late. His tank is set up with one basking rock/hide (its a cave with the top flat for basking) on the warm side with a heating lamp pointing toward that hide. Then there is a smaller cave hide in the center of the tank and on the other end there is his water dish which is big enough for him to get in if he wants (though he doesn't).

Any advice about getting him to start eating?

He hasn't lost any weight, though I don't have a scale so I don't know that for sure..
