I know someone that fed a F/T to his snake and the snake died!
Does this mean people should not feed F/T?
The bottom line is to feed what works and what is convenient to the owner, but to do so RESPONSIBLY.
There is no Live vs F/T debate.
I feed over 100 of preys each month and none of my snakes ever sustained any injury.
Usually when there is a problem and a snake dies, it ultimately comes back down to the owner and his methods.
If done responsibly both live and F/T can be done safely, if done irresponsibly both can be dangerous.
