Just a thought. Op has had the snake for two months. Has fed four times in two weeks, not counting the refusals. That's quite a bit of food for a bp, so some refusals right now are well, okay. So it's eaten four times, and from what I can tell, 2 or three refusals. That's a lot of commotion for a bp who is really still just settling in.
I think we should just leave the snake alone for a week with no handling. And space out the feedings a bit more.
