I just heard about this extremely modern, molded fiberglass pet product called the Zen Hideaway. The small version is sized perfectly for cats and can serve to conceal the litter box or to provide a private napping spot. The door is removable allowing kitty to come and go as he pleases. With its glass inset top, the Zen Hideaway could easily make a cool modern end table. Available in black, white, mint (shown above), and deep red.
Thanks to moderncat friend Lisa for the heads-up on this great new product.
