EDGEWATER — Having a pet in the workplace is one of the best perks of a job, and on the city's Far North Side it's a common sight.

What other employee can help decrease absenteeism while increasing job satisfaction, as well as being able to exterminate an average of 21 small rodents a year for free?

Surely only a cat, or dog.

Studies have shown the psychological and emotional benefits of bringing a dog to work, and researchers studying domestic cats have found even indoor felines are fierce hunters.

Several business organizations, like the Rogers Park Business Alliance and Andersonville Chamber of Commerce, have employees who regularly bring their beloved pooches to the office, while Boxers and Boston Terriers can be found in more unconventional places — like a craft cocktail and beer lounge.

Ally Brisbin and Stuart Marsh, owners of 3-D printing studio Edgewater Workbench, said they took in a fluffy, long-haired stray two other local business employees found at the beach because they knew they spent more time at their store than at home.

"If we had a cat at home, he'd be awfully lonely and we wouldn't get to enjoy him," Brisbin said.

She said a few regulars now stop in a few times a week just to check in on the "mini-celebrity."
