no but i have heard of this happening idk why but my Cinnamon for a short time was trying to eat live mice with out constricting them i think he realized it wasnt workin out and he started constricting and my female spider at first had some issues with aiming while striking cuz of her wobble so i would just pre kill the mice but now she has amazing aim she suprised me the other day by taking the fight from one side of her tub all the way to the other side she didnt strike and come back or strike and stay she (in football terms) tackled through her opponent lol it was awesome to see that from her

i guess some snakes just prefer to eat lazy like that but maybe he/she will change their ways and eat like they should
