I feed all my snakes every 5 days until they reach about 500 grams. All my snakes that are going to breed I will continue to feed until the desired weight. Then they get switch back to every 7 days. It also depends on the the snake I have one female who seems to do better on a 6 day schedule. I try every 5, some times she eats sometimes she wont, but she stays pretty consistent on the 6 day schedule.
