Macavity's a Mystery Cat: he's called the Hidden Paw -
For he's the master criminal who can defy the Law.
He's the bafflement of Scotland Yard, the Flying Squad's despair:
For when they reach the scene of crime - Macavity's not there!

Macavity, Macavity, there's no one like Macavity,
He's broken every human law, he breaks the law of gravity.
His powers of levitation would make a fakir stare,
And when you reach the scene of crime - Macavity's not there!
You may seek him in the basement, you may look up in the air -
But I tell you once and once again, Macavity's not there!
