I'm also somewhat new to this, but here's my experience so far:
My BP is very heat sensitive at feeding also, if the F/T mouse is very warm, he'll strike within a few seconds, if not may not strike at all until I re-warm it for him. I started using a feed box (Xlarge Sterlite shoe box) after switching from repti-carpet to aspen, just for piece of mind. After he takes the food I leave him be till the mouse is fully consumed and he starts exploring the box before putting him back in enclosure. Have had no issues with refusing to eat (once properly warmed) or re-gurge. Just experiment till find what works best for you and your snake.
