That's what I have been doing only i've been running them under hot water over and over. Most of the time they will show interest by flickering their tongues and smelling them. Other times they act like they don't want anything to do with them. Whether they end up taking it or not, I always end up going through this for up to a half hour with each of these snakes on every feeding day. Neither of these snakes will ever actually strike at the prey, either. They just take them slowly and gently...
