I have some friends who lived on the 2nd story with one high energy cat and one lower energy one. Both the cats would spend time out on the balcony and not once did either one ever jump off.
I did see a lot of people in the complex put up chickwire to make sure animals stayed in. I would say put up chickwire and you would be fine. Cats are not exactly stupid and I do not see them jumping off something that would be a fall to their deaths.
