I'm wondering if your snakes are quick to strike live prey or if they have to work up the nerve to strike. One of my ladies is completely terrified of live prey while the other will strike if she is given sufficient time and the prey remains motionless while she is debating. I used to watch Snakebytes on youtube and some of those snakes would come up out of the tubs after the rat. I know it was probably edited to show the only the most spectacular feedings, but it makes me wonder what typical python attacks are like.
