WOW! I didn't realize you had 13 cats. I thought you had "only" 9. I like the idea of the cat doors so the dogs can't get in. (Not relevant to me since I only have a cat, but I thought it made a lot of sense.)
tinygeekcrafter: I have a question -- how do you stay so free of cat hair. My cat sheds like crazy (even after I defurminate him) and I have cat hair on every piece of clothing I own no matter what I do.
