I feed my guy in a separate tub, But after he eats and moves the prey all the way down, I carefully move him back I leave him alone until he decides it is time to come out !
It's basically so there's no chance they will regugitate there meal. But, (for me) I've held my bp's,anacondas and retic the next day after a feeding. Nothing's ever happen I'm just super careful with there bellies. I usually wait thou because there not really active then.
