I feed all of my snakes multiple items at feed time, either multiple weaned rats fir my larger girls or multiple ASFs. And I pretty much offer food til they refuse. Snakes are dumb but they will eat when hungry and not eat when full (or on one of their damn ghandi like hunger strikes).
It isn't damaging at all to the snakes.
"power feeding" is the abhorant practice of sticking multiple prey items in a snake at one time, basically tricking it in to eating more than it planned / wanted to / than is good for it.
It is completely different from a weight building feeding schedule. Which is what I have all my snakes on. They are all kept in good temps with good humidity and offered an all you can eat buffet every 5-7 days.
Thanks for the help I may try that a couple times to see how things go!
