I just love how cats have their own attitudes.

You do not pet a cat...it allows you to pet it.

I am really sure that cats own people.
My wife told me that one of her friends at work adopted a cat and it acted real strange opening her door to her bedroom at night, and she would wake up with it staring at her...lol
She got a little worried when it started pawing at the air above it's head, and thought perhaps it had ear mites.So she took the cat to the vet, and found out it was bi-polar...no kidding.
Now she gives it drugs every day.
She hasn't had a problem since...funny story though.
I had a cat once that would pat at my eyes while i was sleeping.... my eyelids twitching from a dream no doubt.
Perhaps trying to wake me..i do not know.
