I have two cats, and I love them more than almost anything in the world. But at the same time, I'll be the first to admit they're the biggest jerks in the world. They expect us to do everything for them, and then they get to decide if we get their attention or not.
But in the end, cats are the most lovable jerks in the world. We still love them to death, even when they...well, when they do things like this.
