Where we lived before, in Port Hueneme, Ca., she would sometimes disappear for many hours at a time. We would look all over the house and couldn't find her anywhere! Then, suddenly we would find her sitting right out in the open where she couldn't have possibly been just a few minutes ago. This lead us to the theory that she was an alien spy, gathering information about humans and reporting back to the mothership at regular intervals. A theory which we never conclusively disproved.
She died December, 22, 2004 while enjoying the outside.
