Ikea UK created a new commercial, featuring 100 house cats, many from employees, that were released into an Ikea store, in Wembley, England, at night after customers had left. These cats are not stunt animals, and the point was to see how, and where, in the Ikea store, loaded with Ikea home furnishings, would make themselves "at home." They had the owners on site, five camera teams (including an infra red camera), vets and professional cat-wranglers, all on hand, and they blocked off parts of the store. The music in the commercial is "Pianni," by Mara Carlyle. It's quite interesting to watch the difference between the cats as individuals, and the extreme difference in behavior between the adults cats, and the kittens. There's a second video embedded below with a behind-the-scenes look at the actual filming.
