I had one cat that fell off the second floor landing railing and dropped about 14 feet straight down onto my glass-topped dining room table 3 times - that I saw.
After that, I moved the couch into the drop zone.
An Aunt and Uncle had a cat that would get on their roof, and then cry. I was concerned, but they said the cat always got itself down.
Later I was outside, and noticed the cat wriggle around (like scratching it's back?) on the roof, near the edge. Shortly after there was a light thud, and shortly after that
I saw the cat on the ground.
Inside, later, I heard the piteous meowing again, followed medium shortly by another light thud.
My interpretation is that the cat wouldn't jump
down, but had just enough thought process to realize that every time she rolled around on the roof she got herself down.
