Ok, update...

He's doing much better. Emily, that's pretty much what I've done now. I moved him out of the herp room because it was getting so warm in there. He has no heating equipment on him because of this. He's now in the hubby's office which is holding steady at 77 degrees.

Now as to why there was so much in his mouth, I haven't a clue. He's not a big insect eater at all. I fed him one cricket the day he came home with me and that's it. Everything else also appears normal. He has been eating and going to the bathroom.

So for now he's staying on paper towels. I plan on weighing him later to check for weight loss, but only when I think it won't stress him too much. But otherwise he's looking really good. Sticking to the side of the kritter keeper and acting normal. There was a point when I thoughtnhe wasn't going to make it through the night. But now Im way more hopeful.
