My Pet Wants a Pet

Once there was a boy who wanted something to take care of. Something of his very own. He begged his mother for a puppy. Until she said YES! The boy loved his puppy. He fed him and played with him and cuddled him. But soon, the dog wanted something to take care of--something of his very own. So the dog gets a pet cat; then the cat gets a pet bird; the bird gets a pet worm; the worm gets a pet flea . . . and on and on it goes as utter chaos ensues.
