well on a sidenote I feed my Bp in a seperate tub and he doesnt get stressed at all, in fact as soon as he goes in he knows whats up.

did you get the snake from a breeder? if so ask if they were feeding live.

Long story short, I got my baby bp and wanted to go frozen but she had him on live, and he wouldnt take it at all. He didnt eat for 3 weeks. Then I brought him in to the local pet store and they helped me with my first live feeding and he ate 2 right away.

As babies they need the live feeding stimulation it seems, maybe not for all of them but for most anyhow.

Put the mouse beside the viv for like 30 minutes and then watch the difference in attitude.

Good Luck, and don't stress out they can generally go a while without food.
