The Cat Who Played Piano

There was a cat who played piano, And the story I tell is true, But he wouldn't play for me, And he wouldn't play for you. He played only for the dog, Who thought it a hilarious sight, But the cat played only for him, And he only played at night. The neighbors were quite puzzled, For it was very late, you see, But the cat cared not at all, For he had nowhere to be. So the cat walked up and down, On those keys so gently, And quite on purpose, and not accidentally. The dog wagged his tail, when cat outstretched his paws, And they both enjoyed the concert, to only dog's applause.
