I would venture a guess Tiffany that shedding is not specifically triggered by a certain size meal. The shedding process i would guess is triggered naturally for the animal based on growth, skin cell receptors, hormone levels from growth and when these things line up the brain triggers the natural shedding process to occur to prepare for the bigger animal. I do not know all the things that trigger the response but just like us our body has automatic responses to stimulis which triggers a response, in this case when the moons align for the bp the shedding process begins. Not sure if that made sense
