I feed every week. Unless they have sausage butt. I feed them once they have poo'd at that point.
Managing size is one thing, but trying to keep them from growing because of you personal desire for her size to stay where it's at is unethical.
A snake should grow to its genetic potential, not be stunted because we like a smaller snake. Also a snake does not grow to the size of its enclosure. Feeding and temp has everything to do with growth rate, as well as genetics and condition of the snakes health.
Do your snake a favor and feed appropriate sized meals at appropriate intervals. If your snake fits in a 40g breeder and you think that is big, I can almost guarantee it isn't ready or healthy for it to go to a 2 week schedule. Every 5-7 days is appropriate for a smaller snake, whereas adults can safely switch over to 10-14 day schedule if it has good weight and muscle tone.
What kind of snake again, how old? How big? Weight?
