Afterthought: in case you never noticed, avoid "approaching" the snake with the prey...you want to give it some subtle motion & wiggle to attract the snake's
attention, but deliberately go past, not "at" the snake. Rodents don't volunteer to be meals in the wild, & while that apparent boldness may delight some braver
snakes (like boas, rat snakes, Pituophis, etc) it's apt to backfire with a shy "ambush" hunter like a ball python. (use feeding tongs also, to keep your own scent
off the prey)
I think snakes have their own personalities when it comes to feeding too...pay attention to what works for yours. For example, many snakes will turn & snap
at a rodent that taps their neck, & may then proceed to coil & eat it, but others (like most BPs) would be "horrified" if that were to happen.
