If you really love your snake don't feed it live... yes its cool to watch for some people but its even cooler if you don't have to visit the vet because of a rodent bite... Feed pre-killed I'm pretty sure it will take it or just feed frozen thawed... & if you're still going to keep feeding live by all means yes interfere when it doesn't grab the rodent by the head... another trick you can try when feeding live is to grab the rodent by the tail & dangle it in front of the snake & I can almost guarantee that it will grab it by the head... Good luck & make the right choice
