Actually she is lying on one of the 1 foot wide catwalks I've had build at various levels on the walls in my apartment (because it's small and I have 4 cats, so I thought this was a good way of giving them some extra space, and the furbabies love them), so my cats can literally run around right underneath the ceiling.
