I used to..for about the first year....
then one day she saw her reflection in the glass-front of my electric fireplace and went nuts barking at herself like a crazy dog. Since then, ANY dog on tv (even an animated one for a local carpet company!). Then, squirrels, birds, leaves blowing...anything she could see moving outside....the neighbor mowing his lawn, getting his mail, pulling in his driveway.
She is superior to any home alarm system I've ever owned at any house I've ever lived in!
....I really should contact my insurance agent and see if I can get an extra home security discount for having her.
