I have a few that strike dead on, and a few that you start to wonder if they are "special" because of how long it takes them to get the mouse. One female gets so wound up that if she doesn't get a good hold on the f/t I have to be careful because then she'll decide my thigh looks just as good. She's an extremely aggressive feeder. I have another one that will try and try, and eventually I just have to lay the mouse by his head so he will eat it.
