I always feed in her tank. Usually when I get home with a rat, shes quick to pop her head out of her hide, and jump straight to that typical "S" shape, waiting for me to drop the rat in so she can strike. I don't know how she knows, but she does! On a rare occasion, I'll have to lift her hide that she's asleep in, and take it out of the tank, give her a minute to start moving, then drop the rat in, and she strikes right away.
