If you want an animal that eat with consistency do not over feed.
Feed an appropriate size prey each week.
An appropriate size prey is a prey as big as your snake's girth size when it comes to hatchling and juvies.
Adult definitely do not need 10% to 15% of ther body weight to thrive, prey between 80 to 120 grams are plenty enough for a large female and when it comes to males a prey that is about 65 grams will be enough.
