That's a pretty good thought! When he was being insanely crazy over horn worms, the last one he had was a little on the larger size. I know they can bite when they get bigger, or pinch (whatever it is, it's not pleasant ?) so I'm careful of that. But this one did something because when he got it, he threw his head over to the left, kinda like he was trying to smash it (the worm) against the vine or something. It was like watching WWF ?Hmmm... Possible issue with his mouth, teeth, or throat? That might cause him to hold out until he's starving & can't stand it, or it heals just enough between times he eats, then gets aggravated again? Might also explain all the drinking—feels good on whatever may hurt?
Of course I'm just spitballin' here. I think we're all brainstorming trying to help. ?
There's nothing visible that I could see, but maybe it bit his tounge?
That was a while ago, like a month at least.
