If a snake was blue on a feeding day (Monday) and and shed out on Wednesday, would you wait until Monday to feed or feed that day?
Personally, I feel a little bad about making them wait. I'd rather have him on the same schedule and not put him off feed by feeding Wednesday and offering again Monday.
*Edit* Then again, a five day schedule isn't too bad for a guy who just went back on feed after a 10 month fast.
