Most anyone who has a cat has had someone ask them, "Have you ever heard of the Cats' House?"
Bob Walker and Francis Mooney began modifying their California home in 1987 to accommodate their feline family members. Now, nineteen years later, it includes one hundred and forty feet of overhead walkway, cat tunnels, cat friendly artwork, and of course, quite a few cats.
Take a tour of the Cats' House at their frequently updated website, complete with pictures of the ongoing construction, as well as shots of the lucky felines enjoying their less than humble abode.
For ideas on how you can make some cat-friendly adjustments in your own home, you can pickup their book, The Cats' House
, at Amazon for $12.89.
But, if you're not a handy cat fancier, here are three must have items to help you get started on your own cat house. 
First, you need the Zebra Zoo Kitty Gym, a six foot plus jungle gym, covered in carpet, rather than faux fur, for durability and style. $399 at PlaytimeWorkshop.com
Second, you need functional cat art, like this Charisma Light Switch Plate, just $10 at

Lastly, pickup the Kitty Cat Circus. Springy catnip toys will have your cat mesmerized. Available at The Cat Connection for $24.99
Don't deprive your kitty of a kingdom fit for a cat!
