A Cat was growing very thin. As you might have guessed, he wasn't getting enough to eat. One day, he heard that some Birds in the neighborhood were ailing and needed a doctor. So, he put on a pair of spectacles, and with a leather box in his hand, knocked at the door of the Birds' home.

The Birds peeped out, and Dr. Cat, with much solicitude, asked how they were. He would be very happy to give them some medicine.

"Tweet, tweet," laughed the Birds. "Very smart, aren't you? We are very well, thank you, and more so, if you only keep away from here."
