Cat Shelf Wall

This was a recycling project I undertook to repurpose lumber from an old shoe rack I inherited from a friend who moved. I decided to use the 1x10's as platforms and the 1x3's as a frame. The 2x2's formed angle brackets, and I filled out the rest with scraps of 3/4" plywood from work. The backing is a section of cheap carpet. The shelves are offset and spaced vertically 12" top to top. Maggie and Petra (the cats) seem to thoroughly enjoy it.
