My 230g pied bp girl gets around a 36g live rat fuzzy every 4 days and my 5ft red tail boa girl gets a medium to large rat which I prekill every 2 weeks or so. I just open the bp cage and she goes nuts and pops out of her bowl hide and stands up ready to assault anything I put in. My red tail paces the front of her cage door. When I open it. she pops her head out and I just dangle the rat by the tail with my hand blocked by the top of cage so she cant tag me and she just grabs it and wraps it up and then hangs half out of the cage while swallowing it. Then when done, she slithers back in under her RHP and curls up.
