I like to hold off feeding when I see a 'shed' coming: besides possibly wasting the food, some snakes will have messed up sheds (stuck & in a zillion pieces)
because for some reason they don't multi-task very well. Keep in mind that younger snakes in great health often have no problem, but others, either older or
with issues you don't even know about are the ones that have trouble: this is because both shedding and digestion requires extra hydration, and doing both
at the same time is more than some can do easily.
