Try this trick, take a F/T rat, leave it in the room for a few hours(around 8 hours), then take a hair dryer, and blow the air on the rat, but blow the air toward her tub, will scent her whole tub, and should cause a here instincts to kick in and come looking for dinner heat the rat to about 100 body and 110 head. did this with my pied male who was a live mouser when i got him, he has not touched live or a mouse since i got him because of this little trick.
