Baiscally from what I have read, Ball Pyhtons do naot eat naturally when they are shedding. SO most likely the recomednation of feeding not feeding them while they are shedding is probably more for people feeding live prey, because the snake might not want to kill it and will end up being hurt. Thye just don't want to eat. Lots of animals that shed/molt always avoid eating when they are undergoing this process. It probably beasue that is when they are most vulnerable. I guess its sorta hard to undersand with snakes since they do not seem to be incapacitated by shedding their skin.
