Guess I'll chime in and agree with the other responses. I have a 1-liter plastic cup from a football game that's my dedicated-mouse-thawing cup. I fill it nearly full, and microwave to a temp of 120-130 Fahrenheit. If the water is too hot, you may partially cook the mouse, which I understand is difficult for corns to digest. My one experience with too-hot water resulted in my one experience with a regurge. If the water is too cool the inner part of the mouse may not thaw, causing digestive problems for your snake. I drop the mice in, do something else, and feed in half and hour or so. It probably doesn't take that long to thaw, but I'd rather err on the side of caution.
