A happy cat and happier books

Just a quick post to show two of SonShineIn's projects. The first was to protect our excess books, which were stored on plastic shelving units in the basement, from the depredations caused by the cat's climbing and the dog's jumping. The idea was from Onkel Hankie Pants but most of the execution was from our own briefly-resident carpenter. Here it is:
Rusty is in the picture, trying to track the cat, who (he thinks) has disappeared. If you click to enlarge the photo, you can see the nice handles for opening; what you can't see is a caster that helps the fencing swing smoothly.
Why has the cat disappeared? SonShineIn also built her a wonderful cat tower so she can escape the dog and look out the window. I have not yet completed my task of stapling carpet on it, but she has found her special perch. Here she is:
The perch in which she's sitting (look for a round fluffy calico object, that's Heidi) was once part of a rather odd little seat that pulled out from our kitchen peninsula, probably for a small child to sit on. We now use that portion for our kitchen wastebasket. Another of the perches was a drawer front from a deceased file cabinet. I love when we can reuse things this way. Thanks again, SonShineIn!
