Double check temps, hides etc.....basically overall cage conditions. The little high white pied girl I got from Petsmart on black Friday was said to be a problem feeder and they had to assist feed her yet today after 2 days of having her, she went crazy and struck and ate a live pinkie mouse. How long have you had George? I'd give it a month or so before I'd really get worried and set up a vet visit. Give him time to get his system sorted out and everything to get back on track. Also if you have a regular reptile vet you see, a lot of times you can get a fecal container from them and just drop off a fresh fecal to get checked.
