Not sure how old she is, but sometimes it helps to go even smaller with the prey item....maybe a fuzzy mouse if she's a baby. Also, try feeding her in a small plastic container if she's a baby. I mean something that's too small to keep her in for too long. Leave her in there with a fuzzy mouse (or appropriate sized small prey) for a few hours (air holes..don't forget em) covered with a towel or shirt so it's completely dark. Don't open up to check to see if she has eaten until the time is up. I have not had that issue with a bp, but it worked like a charm with a non feeding baby corn. Good luck and let us know if she eats.
