I agree with the above post switch to a smaller meal for your BP. Have you ever heard of Ivan Pavlov's theory of conditioning? Basically he was able to get a group of dogs to heavily salivate whenever a bell was rang. This type of feeding conditioning could also work with your snake. Whenever I'm ready to feed my snakes I use a que. I always tap on the bottom of the outside of their tank very lightly. It helps alert the snake the food is on the way and to be prepared for a meal and I've had very good feeding responses because of this. It does work people, but it does take time to develop conditioning like this (it took my bp 8 months feeding regularly to establish this type of response from the tapping, it took my corn only 3 months because she is a quick learner lol). I'm not an expert so take my opinion for what its worth and good luck
