I've done that. i normally bag them up, and in a tall tuperware i thaw and heat them. then as i've had issues with the youngsters hitting the middles, i heat the head up a bit more.

Some one said to just get a medium mouse and just stuff it in, that seems a bit barberic(sp) though. This would get the gut a bit of something and start the appitite.

I'm not going to worry about it though. could be nothing...
