If you want to pamper your pets, who cares what others think? We don't have kids and aren't going to have any, either. I love that room!
Our boys have their own room with a bunch of toys, "popup" cubes, scratchy boxes, and a window to look out. They go there if (non-cat people) company is over or we have a repairman. Of course, they have spots in the living room, and sleep on our bed too.
(this is a no-no place but I had to take a pic before I chased him down!
