A couple of things, Dutch. If he's eating without constricting, at least he's eating, right? It's better than the alternative. You know I feed only F/T at this time since all my guys will take it, and every once in a while, one of them will just ease over and eat it with out striking...then the next week they'll hit it like a dump truck. As long as they're eating, I try not to stress out about it too much.

Also, before you make the change to the tub, you could try crumpling up some big balls of newspaper and putting them in the cage. Might give the snake a feeling of being in a smaller enclosure. That way you can still have all the cage furniture you need in there.
