I thaw mine in hot water from the tap. Then dry them off. The first couple of times I had to do the "mouse dance" to get them to eat it. Now all I do is put them in their feeding container and drop the mouse in there and they eat it just fine. I got lucky in that all my bps will take f/t this way.

The biggest thing is to make sure that the mouse is warm. For the first couple of times I would use forceps to do the mouse dance. Don't be frusturated though if he doesn't take it right away or at all. Good luck.
