If your front door is in a bit of a hallway (inside the house/apartment), try putting up a baby gate at the end. Yes, kitty is going to jump over it, but it's an extra obstacle that'll slow kitty down a bit and give you a couple extra seconds to react/anticipate. <-- This one worked for Grr until she got bored with the 'game' and stopped trying to run out
If you're willing to deal with part of the apartment smelling like an old lady's closet, a moth ball wrapped in a bit of cloth (or a sock) and hung from the doorknob can also help. -Most- cats are repelled by the smell, and it'll also help override any "come hither"s left by a wandering female coming in from that direction. Â <-- This one worked for Cela
Come summertime (or anytime of the year where it's nice enough that you can leave your windows open for extended periods of time), you can make a sort of window-box that kitty can go hang out in -- it's basically a crate that had one side removed and a small frame added to keep it in the window. Put in some of those cat-safe plants Arrelaine mentioned, and it's a 'safe' outdoors for kitty to play in. If you're on the first floor and have permission from the landlord, you can make something bigger fairly easily.
