This is a link to a detailed 99% accurate tracking of my one ball python Lilly, All of her feedings shedding are 100% accurate. I may have missed a (poo) or recently but you can tell by the labeled poos! how far apart they are. Off the top of my head not looking at the tracking list i am pretty sure she went twenty nine days with out going!
