A CAT, hearing that the Birds in a certain aviary1 were ailing

　　dressed himself up as a physician, and, taking his cane2 and a bag

　　of instruments becoming his profession, went to call on them. He

　　knocked at the door and inquired of the inmates3 how they all did,

　　saying that if they were ill, he would be happy to prescribe for

　　them and cure them. They replied, "We are all very well, and

　　shall continue so, if you will only be good enough to go away,

　　and leave us as we are."
