FatBoy, I had made the assumption that this was a snake he had for a long time, and that it had been eating and doing fine prior to this, and hadn't been moved. If that's not the case, then of course you're right, and simple stress could be the issue.

I've had newly acquired snakes take as long as 3 months to start feeding, and nothing was wrong except they just didn't feel comfortable yet in their new home.

I've also had newly acquired snakes eat the day after they arrived--they certainly are all individuals!
