Gee, that was really dumb of them to feed him right before the move...but I suppose they thought they were doing a good thing.

I'm glad he got there safe & sound...let him rest & relax (if that's possible for him?) Can you imagine how much more stressed he'd be in a different cage
right now? I wouldn't worry about taking pictures or getting his weight or anything...that could make him regurgitate his meal. Wait until he has digested
this meal, at the very least. (I'd wait until he soils his cage.)

Congratulations on your new beautiful ball python!
