The Safe Haven Pet Sanctuary in Green Bay, Wis., has been blessed with one of America's most helpful volunteers: a brother at the St. Norbert Abbey named Terry Lauerman, a 76-year-old retired teacher who started coming in to brush the shelter's special needs cats. But his mission quickly turns to slumber, and soon photos of Lauerman's cat naps with the felines went viral. Steve Hartman reports.
