"When street traffic dwindles and most people are sleeping, some New York neighborhoods begin to crawl with cats. They move quickly through the shadows of building; night watchmen, policemen, garbage collectors and other nocturnal wanderers see them — but never for very long. A majority of them hang around the fish markets, in Greenwich Village and in the East and West Side neighborhoods where garbage can abound. No part of the city is without its strays, however, and all-night garage attendants in such busy neighborhood as Fifty-fourth Street have counted as many as twenty of then around the Ziegfeld Theatre early in the morning. Troops of cats patrol the waterfront piers at night searching for rats. Subway trackwalkers have discovered cats living in the darkness. They seem never to get hit by trains, though some are occasionally liquidated by the third Rail. About twenty-five cats live 75 feet below the west end of Grand Central Terminal, are fed by the underground workers, and never wander up into the daylight."
Gay Talese 1961
