Cats are narcissistic. Their needs come before ours. They don't understand the word "No." They carry themselves with that aloof, arrogant sense of perpetual entitlement, they will jump up and insinuate themselves wherever they please--on your lap, on your newspaper, on your computer keyboard--and they really couldn't care less how their behavior affects the people in their lives. I've had boyfriends like this; who needs such behavior in a housepet?
