Any cat would give up one of its nine lives for a shot at living in the Cats House, a wacky fantasyland for cats created by Bob Walker and his wife, Frances Mooney. They've turned their California home into a feline fun house. It's the perfect mix of cat-friendly and cat-fantasy. The house is all cat, and nine of them call it home. Bob Walker shows us the cats living space, giving us a peek into 140 feet of brightly coloured aerial walkways, spiral staircases, giant scratching posts, and playful peepholes.
