What you have to remember is this is not a year around feeding schedule. It usually only lasts a few months say from may -Oct/Nov. When they are in shed I do not offer food. So they get breaks. This schedule is only on the girls I feel have a real good chance at breeding the up coming season.
People are use to hearing to feed once a week. That is fine if you are happy fewer females going and having more slugs in the clutches. You can not over feed them. That is as long as you plan to breed them. If you have a pet ball python then one small -med rat a week is perfect for a pet snake.
Good luck this season.
P.S. No offense taking
