We got back last night from NC and found a great two bedroom/two bath apartment with a study. Third floor, cathedral ceilings...so nice! My question is: this will be the first time we own a patio and I would really like to let the kitties go outside on it. What are my chances of them trying to jump from the 3rd floor? Is it just unwise to even let them out there? I'm terrified of them jumping on the railing and falling off.
