My red tail boa loves to eat her medium rats like that. I open the cage door, hang the rat in the doorway with my hand above the door frame and she grabs the rat and then lets it hang out of the cage and half her body hanging out the cage too like the last pic of your BP. After she is done, she slithers back in and goes to her hide and curls up lol. She is most laidback lap snake I have ever seen.
