Could have sworn I read it on here before, but I didn't know what to search for in order to find it, so sorry if (I know it probably has ) it has been asked before...

What is the general rule for feeding amount? Not the "widest part of the snake" but weight percentage... I thought I read 10 or 15% of the snake's weight at one time, but again, didn't know how to search for it :/

thanks
