Haha, I just throw in some ammonia, test it, and leave it for a week or so then test again just so I'm sure that I'm not starving the bacteria once all the ammonia's gone. It's not that hard...well, except the waiting part lol!
I actually get neurotic when I'm using uncycled tanks (like the ones I've had to use to QT my new bettas). I'm like changing 50% of the water every few days and constantly checking ammonia despite the fact that they hold about 4 gallons apiece.
And no stealing my fish! Geesh, I'm going to have to fortify my room *hurries over to make sure all bettas are still there* and maybe train him to bite all intruders! Bettas...attack!
