The 18-month-old from North Carolina won the Cat Fanciers' Association-Iams Championship at Madison Square Garden on Sunday night.
Named Runner, the feline was the first of his breed to nab the prize.
With a shiny, velvety gray coat and green eyes, Runner competed against hundreds of cats for the Best of the Best title.
The 12-pounder won 400 pounds of cat food - and a national appearance Monday morning on "Live with Regis and Kelly."
For fun, there was another contest alongside the championship, pitting a Bombay named Barack Obama against a Republican stand-in named Renegade - a British Shorthair representing John McCain. The Obama cat won 2-to-1.
