ok Im going to tell you exactly what to do ... I had the same problem a long time ago take your snake and the mouse/rat pup put them both in a small box ....if its smalll enough a shoebox close the lid and leave them in there for 30 dont open for 30 min and hopefully it will eat .....it worked for me with my first BP the only downfall to that was now when I feed that BP i put it in a plastic tub with a lid and have to cover that with a blanket ,,it has to eat in the dark. Good Luck hope i could help
