The Tail of a Neurotic Cat named Licorice

One of my parents cats,Licorice, patiently waits by the front door of their home everyday. Surely waiting for food or her owners to get home right? No....She's waiting for my Dad to use his lazer pointer. It's gotten to the point that I have caught this poor cat with her nose right in the corner by the door as if she was some kind of German pointer. She was so still she could have been confused for one of those scrubbers that you use to clean your boots off after you come inside from the rain and mud.The worst was when she starting chasing the lazer pointer that wasn't there. Is it possible to drive a cat insane I wonder?
