My Cat Just Sleeps

My friends have all got fun cats. They jump, and chase, and play and hunt. But my cat doesn't do any of those things. My cat just sleeps. A charming story of one little girl and her beloved, sleepy cat. She can't help but compare him to all her friends' cats who do exciting things, when all her cat does is snooze. But why exactly is he so sleepy? Is there something about him that his owner doesn't know?
