A little insight on what to do if snake won't eat

[Bogertophis]

First question has to be: how much are you handling this snake? Good rule to follow: NO handling until a snake eats at least 3 meals for you at normal intervals, without any refusals (unless in shed cycle, then don't expect them to eat & don't even offer, just wait until they're done shedding).

Everybody that buys a pet snake can't wait to hold them, but remember that the only thing in the wild that normally picks them up is a PREDATOR that's about to EAT THEM! So needless to say, fear tends to ruin their appetite for food. You must always let them "be a snake first". Eating is Job #1.

Another thing: how often are you offering food to this snake? If they refuse a meal, don't offer again for a week, as offering too frequently just stresses them into refusing. If they refuse after a week a few times, then wait 2 weeks before offering again. Also make SURE their enclosure isn't in a busy location, with too much activity & vibrations or other pets (dogs & cats) nearby that might be intimidating them. New snakes need privacy & time to "settle in"- some just need less than others, just like all humans aren't the same either.

Feed at night- that's when BPs hunt in the wild.

Understand they're ambush-predators- so if your BP is cruising the cage, it's unlikely they'll eat. Best to offer when they're peeking out of their hide in the evening- that's their idea of "hunting".

BPs rely on their heat-sensing pits to find prey. This is crucial for most of them, that if you feed f/t (or even freshly pre-killed) rodents, they are very warm when you offer them. Many find success using a blow-dryer to give dead prey some life-like warmth so the BP will "recognize it" as if live prey.

Some snakes are shyer than others- dim the lights in the room when you feed, & try to be as invisible as you can manage. Use feeding tongs, don't over-do the motion (when you wiggle the prey to get the BP to strike), and it might even help to cover the snake's "view" by covering the enclosure with a towel or tape up paper temporarily so she's not distracted by you nearby.

Understand that BPs are predators, yes, but they are vulnerable when eating to predators that want to eat THEM. If they feel too exposed, they won't eat. That also brings us to your set-up: right temperatures? enough hides & the right types? etc. We cannot offer suggestions to improve what we can't see.
