its what you dont know...
If a cat falls from 2nd or 3rd floors it can be hurt or even killed. However cats falling from above 5th floors or equivalent height can turn in the air and spread their legs wide to catch the breeze - and they always survive (the flaps of skin between upper leg and chest make amazing air-brakes and were probably an evolutionary adaption for that reason).

A cats terminal velocity is only fatal below a certain height. Bit like parachutists in that regard,

Wish I'd known that
Probably would have put more effort into helping the ex when she was flat hunting.

Anything above 2nd or 3rd floor would have encountered strong reservations on my part.

Kidding.

I read an excellent article about this (which I now can't find)
It contained the fantastic line "the only difference between a fall from 100 feet and a fall from 1000 feet for a cat is that is will have a few more seconds to flip off the birds on the way down" :D
