When you thaw out the mice, you do not want to use boiling water.
THAT IS A BAD IDEA.
Warm tap water is plenty fine. I personally run it under hot tap water until it's thawed out completely then blow it with a hair dryer and feed.
You could severely hurt your snake if you gave them mice that were just boiled, because the mouse would be too hot and burn the snake internally. They don't want something cooked.
thanks yall i learned that the hard way lol. but i let the mice cool down before i gave them to the snakes because I seen the heat coming off of them before i gave them to them so thanks a lot for all the advice. From now on its hot tap water lol..
