A few years ago, when Mousie went outside to the garden (pre- the evil doggies), she would always jump up on the glass roof of the kitchen. She would look down on me to see what was goin' on! The pics are hard to make out at first, but if you focus, you can see her - and me taking the pictures.
I believe she was the happiest when she was jumping and climbing.
