You know - if he refuses again on the next feeding, I would wait him out. I'd wait at least 2 weeks before offering him food again. Just keep a very keen eye on him - when you see him "lurking" in his hide - that head peeked out with interest (not in a relaxed, head on the ground pose, but rather with head elevated off the ground and sticking out) - that's when you offer him the next feeding.
Pre-scent for 30 mins and see if he becomes even more "lurky" - more hyper aware. I hope you understand the behavior that I'm trying to describe.![]()
