I think, just like kids, BP's should be fed more often when young, because of the rate of growth. At the same time, I have several animals that would eat on the hour every hour if I let them. Fatty butt snakes.

I feed my WC girl 2 (maybe 3) weaner rats a week (that is a rare occasion she would get 3), she is solid hard muscle, and poops regularly. She is always hunting, on a hair trigger during the day, prowls incessintely at night.

Would I feed my other girls the same amount? Heck no, they would get FAT!
LOL, different metabolisms, different snakes, different feeding behaviors.

It's just a very good rule of thumb to feed one rat (or a few mice) on a schedule. Some snakes need more, some need less.
