Every snake is different but you wont know if you dont try. You never know what was your BPs diet before? Some snakes have sex, color, type of feed preferences. So you never know until you try. The whole live vs f/t will probably be the hard part but it depends on your snake again. I feed live unfortunately cause my girl is wastful but today she got bit. Didnt break the skin cause she wraps the head quick thank god. But struck a little high and has a nice very small red mark and little edema. So that is why f/t is the prefered method. So I say try 1 live adult mouse to not change too much at once and if your BP will eat mice then switch to f/t until its willing/able to take rats. Just remember that mice are actually more likely to bite your snake then a rat. Those things are nuts. So just monitor the feeding as you should always do IMO with live feeds.
