What size rodents are you feeding in comparison to the girth of your ball python? The two main reasons that ball pythons 'fast' are overfeeding and incorrect husbandry. Make sure that you temperatures are 92-94 warm side and 82-84 cool side. Ball pythons have slow metabolism in comparison to some other pythons. Alot of people including myself like to feed prey items that are slightly less than the girth of the ball python. This will help out in having a consistant eater. Hope that helps...
