The Cats' House closes shop in SoCal

This undated photo released courtesy Bob Walker showing cats standing on an elaborate set of cat walks inside of a home in San Diego Calif. Bob Walker and Frances Mooney moved into the house in 1986 and started converting it into a human-sized cat condo with 140 feet of elevated highway, tunnels, ramps, a spiral staircase, rest areas and scenic vistas. It even had a floor to ceiling scratching post. One improvement seemed to lead to another. (AP Photo/Courtesy Bob Walker)
