The shelf area is right at the foot of the stairwell leading up to the bedrooms on the fifth floor. (Multi-level house. Each level is half a floor higher than the previous.)
Firestar IS able to reach the short wall which separates the living room from the kitchen. It's an eight foot wall, but we have a vaulted ceiling. You can make out the shadows from the kitchen lights behind Firestar. A Lord of the Rings poster decorates the wall below Firestar. There's a poster of Puss 'n Boots beside it. Spouse's desk is stright down.
