What was the pet store feeding it before you got it? F/T or live? Mine was being fed live so thats what I stuck with. What I have done the two times I have attemted to feed mine was, keep the mouse in its little carry box and place it in the snake feeding 10gal. I have. Then I place my snake in the 10gal. and cover all but one side with a blanket. I place my CHE on top for some warmth and leave the room for 15-30 minutes. When I come back my bp is wrapped around the mouse box anxious to eat. I take the box out and place the mouse in and he takes it within a few seconds to minutes everytime so far. It works for me at least. I don't know if you would just rather do F/T or not but I prefer live. I just fill like I have a better chance of having my bp feed plus he was already use to it. It's an idea at least. Also what size mouse are you trying to feed? make sure it's the apropriate size for you bp. Hope this helps.
