Here was the Backyard Oasis, which also had the cat perched happily in it. He (or she?) seemed pleased that so many people were stopping by to admire.
The cat is that white blob in the center of the picture. There are apparently three more cats who were not around to be viewed.
The couple who had this built recommend galvanized wire. They had to paint the ungalvanized wire when it rusted. I also liked the big access points/doors.
