The boy, CuddleFluff, is at top and Noodley the girl is toward the bottom -- both are being actively doted upon by Marcella. Not that they're spoiled or anything. This is a cat room Geoffrey built on a stand that Mary left behind -- she had a slightly different setup for her cats when they lived here. You can see the kitty bridge leading from the house window to the enclosure. It can be closed at night.
The cats love this thing -- they can go out and watch birds or bugs or just hang in the fresh air. I think more and more people are going to have indoor-only cats so enclosures like this one will be common. Marcella's cats travel -- they have their own travel playpen and are accustomed to a leash. They have been up to the ski condo several times and come to hang out at our house often. Sophisticated kitties.
