Wow.
You have to hand it to the orange cat.
The tabby had him pinned, but somehow, the orange one manoeuvred the tabby over to the edge of the roof and then pushed him off the roof. (The orange one even had the wherewithal to swing himself back onto the roof rather than falling with the Tabby.
And just to make matters worse, the orange one drops him into a yard with a rather large dog just waiting for him. (Fortunately, the Tabby appears to have escaped the dim witted dog.)
