I don't mean to thread hijack, but I would just leave him alone for a while first. Only bother to clean/feed. After about a week or 2, you could maybe hold him for a few minutes. If he isn't even slightly better, I'd give it another week.
Note: I would start a new thread and get 10x better suggestions from people who have dealt with more timid snakes :gj:. I've only had to deal with 1. He was stressed after an expo, so I left him alone.. He eventually came around and started striking at his food, instead of waiting til I left to start eating.
Unfortunately he has to be removed from the cage to feed on Thursday(company policy, and the managers who listen to me wont be in unfortunately).
