You really should have surveillance cameras in your house, Astro. That would be perfect for 'Funniest Home Videos'.
Reminds me of an incident with Snoopy when I was back east. Both of my cats were neutered orange toms, which are highly susceptible to getting build-ups of uric acid crystals in their bladders. Hence, they can't be let outside if it's cold or damp.
Our house had an external door to the basement as well as the inside one, and it was housed in a building extension that was only about 9 feet tall (the stairwell roof was just below the 2nd floor bedroom window). The house was done in those pebbled asphalt shingles, which had a good traction surface.
If something alarmed Snoopy when he was outside, and the porch door was shut, he'd run up the side of the house and jump onto the stairwell roof.
So... one winter we had the shingles replaced with aluminum siding.
The first day that he was let out in the spring, a dog barked somewhere and Snoopy came shooting out of the orchard full-tilt. He made his jump and started scrambling. He actually made it to about 7 1/2 feet up, and then suddenly realized that something wasn't quite right. In that split second when his vertical speed was zero, the most hilarious expression of complete bewilderment came over him. It screwed him up so much that he almost forgot to land on his feet.
