Winkie Winkerton left her condo above the sink on June 25 after 11 years of happy living in upstate New York. She was at least 16. The good people at Heart of the Catskills, a humane society in Delhi, drove two hours for a prearranged meet and greet at the Kingston Petco, where I waited with a carrier. “Not everyone wants a senior cat,” said her chauffeur. Since no one picked up the black cat sitting in the next cage, I got her too.
