Honestly I don’t think there is anything wrong with feeding every five days, I’ve even had some of my better eating females eating twice a week. The key is the size of the meal. I like to feed on the smaller size but more frequently for my growing snakes. This is usually just the first year or two. My girls have not got obese and so far they have got to breeding size quicker than average and laid healthy good size clutches with no slugs. So that goes to show you all the negative talk about overfeeding isn’t all true. Now if your pushing the limits of prey size they can eat, then 7-10 days is plenty. I like to feed my adults large prey but some of them only eat every 2-3 weeks. For consistent healthy growth of young ball pythons, a small meal every five days works great.
