My BP's Scale Spot

yea just leave him to eat it as he does i am sure he will be fine.
are you sure it was fully thawed? did you feel the mouse with your fingers to try and feel any cool spots?

I always make a thurough check over with my mice, I keep it in hot, but not boiling water for approximatly an hour, a little longer today, then I blow dry it so the heat from the dryer heats up the head (to attempt to make it an easier target)

just me being a noob XD I dont know if it actually helps, but I hope it does
