You have a marvelous house for cats. This is wonderful...............in Chicago, I lived on the second floor, right next to the garage and my 4 cats would go out on top of the garage....even in the snow. We lived next to Midway airport so they came in quickly when the planes would come and go. So sweet!!!!!!!!!
I rented a condo in Lowell, MA in the early 90's that had a 3rd floor bedroom with a skylight just like that. One day a cat dropped into the room and panicked -- she'd jumped into the wrong condo!! She jumped back out before I had a chance to introduce myself!
