A Cat, hearing that the Birds in a certain aviary were ailing dressed himself up as a physician, and, taking his cane and a bag of instruments becoming his profession, went to call on them. He knocked at the door and inquired of the inmates 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.”

Aesop was an ancient Greek storyteller, believed to have lived around 620–564 BCE, whose fables have shaped moral literature across the world for centuries. "The Cat and the Birds" is a compact example of his recurring theme: that flattery and false pretense are most dangerous when dressed in the costume of helpfulness.
