She lurks in the shadows, watching as I take the bike out the door...or bring in groceries...anything that gives her enough time to appear out of her hiding spot and make a mad dash for the door. We usually run after her. She waits until we get almost to her at the bottom of the stairs, then darts around us to run back up and down the back staircase. Sometimes she takes off down the path to the park. If she makes it to the woods, we'll never find her. She hisses and spits at everyone. No one will take her in if she gets lost.
Until I had an armful of groceries and couldn't chase her right away. I slammed the door shut so the other cat wouldn't get out as well and went to the kitchen to put the groceries on the counter. I heard a scratch and a pitiful, "Mew." I opened the door to find her sitting there with a confused look on her face. "That's not how we play this game..." her expression said. I haven't chased her since.
