Oh, ok. I never knew about any of that. Thank you for the info. If I do feed live, i'll just pay close attention to the snake, and if it's not interested, take the prey out of the cage after 20 - 30 minutes. I'm still not sure which method i'll be doing until I get the snake. If it's feeding fine on live, then i'll continue that method, and might start breeding my own feeders if I have enough snakes to supply that. If not, I can find someone locally that breeds them and go that route.
I do have cats that might consider it a snack, but i'd be more worried about the snake being able to eat first.Plus, I don't want to put the mouse/rat through any more pain than is necessary.
