The immense superiority of cats over mere humans is at its most powerful when we get high up. The higher we go, the more we can look down on them.
And the less likely they are to find us. It's a strange thing but humans often forget to look upwards, when they are trying to discover where we have got to.
And we can sneer at the dogs and the humans below.... if they even notice us.
Look upwards, humans. We are watching your every move. You don't see us: but we see you from a great height.
