My cat acts like she's bipolar. One moment she's nice and the next she'll attack out of nowhere. So when I was little, I didn't think both sides of her personality could possibly be the same cat so I figgured we had 2 cats, that looked exactly the the same, and while one was out wondering the house, the other was hiding in the basment, so we could never see them both at the same time.
