After we dragged our completed cat condo up out of the shop and into the cat's room, we went looking for her to "test it out".  She was hiding in the closet, but we were sure she couldn't wait to see her new house.  

You could taste the excitement in the air.  Or the sawdust.

Placing the cat on the condo was a pointless exercise, much like trying to teach it to fetch, or mix martinis.  We eventually coaxed her up to the main level with her favorite treats.

If you recall, the original design called for a vertical space of no more than 12" between platforms to allow crotchety old Spotcat to get to the top of her house with a minimum of effort.  Naturally, she thought nothing of our considerate design and jumped directly to where the treats were, a full 4' off the floor.

She'll be old someday, and then she'll appreciate us.

We sort of glossed over some of the finer points of building your own cat condo.  We overlooked how to fold carpet in such a way as to make it appear that it actually belongs on (and not as if it is trying to digest) the thing over which it is folded.  We didn't give you any meaningful measurements, we didn't talk about weight distribution, and we never even mentioned power tool safety.

For those of you who are disappointed with us because of this ...
22-1/2" x 18-1/2", put the heavy end on the floor, and don't use a table saw to carve a turkey.
