Generally speaking, though, ball pythons will do well on a once/week schedule throughout their lifetime (that is also easy for a keeper to remember what day feeding day is), which is why I kept that part in there.
Thank you so much! This is perfect info for me. I have been feeding them weekly, on the same day usually, (and believe me, they know the day), and that's the size I have been feeding too. I am glad I don't need to go up a size. It fits my budget too.
