I've just recently switched my snakes over to f/t. everyone has taken one at least once but they dont take them all the time, in which case, i feed them live and they strike. you can always (this might seem mean to some people) flick the mouse or rat in the head really hard with your index finger and knock them out if they start gnawing on your snakes' coils. i've had to do it a couple of times and it saved a couple snakes from a potential open wound. i would prefer to feed all f/t but sometimes its easier and faster to feed live. its pretty much a guaranteed strike with any of my snakes.
