The only reason I've heard that some do not feeding during a shed cycle (in regards to any snake), is because supposedly the lump created by the meal makes it difficult for the snake to pull the shedding skin over it. If that made sense? I wasn't sure how to word that. The lump of the meal creates a "block". I do not know if this is true and I do not know if there are any other reasons why not to feed during the shed cycle, it's simply what I have come across while reading on forums and breeder's pages.
