After a couple minutes, the mouse no longer looks like food to her. Even if it was hot enough to begin with (an hour of room temp defrosting may not be long enough), there's not a snowball's chance that it was hot enough even 5 minutes into your hour long dangling session, let alone the other 55 remaining minutes (who are you, Sting?).
This. Once the animal has cooled off, most snakes aren't going to eat it. some will take cooler prey than others, but room temperature? Not bloody likely. If the animal doesn't feel warm to you, it's not warm enough for the snake.
