I've had BPs that hadn't eaten in 4-5 months after I had bought them (change of environment) when I'd tried everything...then I fed them some dead ASFs and they both went mental. It was like these snakes were possessed. I then gave them a mouse, then a rat and now they're both eating regular rats.
I also had a couple of babies that I was assist feeding. Wouldn't take mice or rats. I had a couple of females ASFs give birth so I threw one in to each of the BPs bins...and bam they took them. They wouldn't take anything but ASFs for about 5 meals and then they switched over to rats.
I have a theory about BPs who haven't eaten for a while...you're going to laugh at me....
Remember when you were young...was there a time when you felt really sick to your stomach because you hadn't eaten in a while? You felt sick because you hadn't eaten but eating was the last thing you wanted to do...then your parents forced "forced" you to eat something that you really liked, had a bit of it, got your appetite back...
I know it's a stretch....I think I think too much. :-)
