Our cats have long enjoyed going out on our deck, which has all the joys of the outside world without most of the dangers (no stairs=no predators and no kitty access to the streets). Waffle has been quite jealous that all of the other cats get to go out there periodically, but we were holding off on letting her out until we were sure she had no desire to leave. Now she's good to go...and she loves it out there.
