I have refrozen a few times, but only once. I know where the rodent is in the bag and its always the next one that gets eaten.
The 24 hr. part may work, I've tried that before and just woke up to a stinky mouse and the snake in it's hide haha. Maybe try that if the snake has never eaten before or if the problem persists, just my opinion. Not sure about eating things that are already dead but haven't decomposed too much, haven't heard that before. Where did you read that? Just interested in knowing.
Thanks
