Ahhh...this is where a nice, gentle defrost over the course of several hours (or even overnight) works well, then maybe an hour or so prior to feeding the snake, place the mouse on its back on a warm (but not hot) heating pad. That way the abdominal skin (which is thin to start with and has already been weakened due to the freezing/thawing process) isn't directly exposed to high heat, but the mouse has an opportunity to come up to "heat signature" temperature.

You may want to play with the thawing time/heat pad temps a bit to find exactly what meets your needs, but try that technique & see if you end up with fewer unexpected explosions of the icky rodent variety.

BTW...that's a "You Might Be A Herper If..." you've EVER had to clean mouse guts off of ANYTHING!!!
