FOUR FERAL felines have found employment at Chicago's Empirical Brewery as rat-catchers, of course. Placed by Tree House Humane Society's Cats at Work program, Venkman, Egon, Raymond and Gozer - nicknamed the Ghostbusters - patrol the grain-filled brewery with cat-astrophic results for rats and other rodents. They're not the only cats in the industry. The Instagram page @distillerycats features working-class cats at other breweries and distilleries as well as at wineries, bars, pubs, cafes and liquor stores. Raise a glass to them next time you're enjoying your favorite spirit.
