Awesome! its always nice when they take that first rat.

Some things to consider, you're not cooking the rat, just thawing it. You can leave it out a few hours to let it thaw and then dip it in the hot water or blast it with the dryer to get it to the right temp. Some people let it thaw under a heat lamp near the enclosure to get the snake hyped up for dinner time. I personally let it thaw in lukewarm water and a blast from the blow dryer near the enclosure starts a feeding frenzy.

Good luck with your next feeding, hope all goes fantastic!
