I haven't ever had to do this but I would like to know the procedure anyway. When using toads or lizards, either for actual feeding or for scenting, what species of toads and lizards are used, and where are they acquired from? Are they wild caught or pet store bought? Can you feed them f/t? How are they killed humanely? I would imagine a c02 gun? and then frozen? Does freezing them and then thawing rid them of parasites?
