When I rushed in, I saw Pole and her pillow had fallen down from the top shelf onto the shelf below it. I am not sure how that happened but I think cat and pillow both fell backwards against the wall, from one shelf onto the other.
Pole looked really upset and was trying her best to "recover" and maintain her calm poise and balance.
Sobs..I fell down...
Never mind, Pole. It's okay to slip and fall down once in a while.
Looks like she doesn't want to get up onto the top shelf anymore!
