I believe 8Ball Adam has documented that over feeding, "Power feeding" as it's known as, will result in a long period of fast. Meaning, your ball will take what's offered to him/her but will eventually go off feed to allow it's body to "catch up". Please correct me if i'm wrong.

I feed all of my ball pythons one meal per week. Depending on size, they may get more than one prey item in a single feeding.
