Cat Castles: 20 cardboard habitats you can build yourself / Carin Oliver, 96 pgs.
This is an absolutely ridiculous book that encourages you to decorate cardboard projects for your cat to sit, lay, sleep, play in. No cat has a need for anything this fancy and I deem this a great book for someone who has too much time on their hands. Now excuse me while I start on my first project. P.S. Also contains fabulous photos of projects in use.
