My BP won't eat if she is in a shedding phase. Others here have said that they wait until after they shed but then a good number also say that when feeding time comes around, they feed, shedding or not. So I think it's going to depend on your BP if they are interested in the prey or not.

My BP will also spend days in her hide, especially when she is about to shed. When I notice the pink belly, I will offer her one more feeding and then leave her alone until after she sheds. So far I've had 4 almost perfect sheds since owning her.
