It happens sometimes ... it's not that they "enjoy it" ... joy is a human emotion not applicable to snakes ... sometimes they just get lazy ... especially if you don't give them time to get into "feed mode" ... they get in this really relaxed state somewhere between "shut down mode" and "feed mode" where they're hungry but not yet totally alert and active and will take prey like that ... sometimes I also see them coiling their prey and constriting it using only their bodies, without biting it while in this state as well.Originally Posted by Snakeman
Totally normal.
