Following the celebrations for Naval Commodore George Dewey in September 1899, the Dewey Arch on Fifth Avenue began to quickly deteriorate. Passing vehicles and carriage wheels made several large holes in the base of the double trophy-columns, and souvenir seekers had also begun chipping off pieces of the arch (bits sold for 15 cents each). But that was just fine for one large grey cat that roamed the streets near Madison Square — a hole in the corner of one of the columns would be the perfect place to give birth to her kittens just before Christmas.
