A breached door redux

I obviously jinxed myself, because this morning at 5 am I was woken by the sound of the door handle twanging open, followed a couple of seconds later by a cat nudging my hand. I put the cat out, but a few seconds later I heard the door open again. I locked the door after I kicked her out this time, but she then proceeded to try to open the door for the next twenty minutes or so, illustrating the fact that extinction does in fact take longer than behavior acquisition. Now I'll just have to keep the door locked for the next several weeks, since periodic reinforcement is the best way to create lasting behaviors (if she gets in every once in a while, she'll keep trying forever).
