Why do cats sulk?

Humans are huge to a cat. When you scold him, you are intimidating him. And when you look down upon a cat to discipline him, he associates your fixed gaze with a rival. The eyes of many animals are a signal of power. In comparison to a cat's size, his eyes are enormous. In hostile situations, a dominant cat will stare at his rival, who will look away rather than increase the hostility. So when your cat turns away after disciplining, he isn't ignoring you; he's surrendering.
