I thought I lived with turtles

You know, turtles. Creatures that can't climb down stairs. This evening I heard G'Kwan in the kitchen fighting himself against my mirrored garbage can, but later I didn't see or hear either turtle. The laundry room used to be part of the garage, and is reached down two stairs from the kitchen. You see where this is going, don't you? I was getting ready for bed when I remembered that I had seen one of my gardening shoes, which I keep near the back door, knocked from its usual place, but I figured that was from the cleaners yesterday. Still, I looked all over the house and found no turtles, so I went into the laundry room, crawled under the sink, and shined a flashlight behind the washing machine. G'Kwan had trapped Dymphna back there. She might have been there since yesterday, in fact, since she hadn't knocked anything except the shoe so I wouldn't have heard her. Anyway, I grabbed both of them and brought them into (different parts of) the main house. Dymphna promptly peed on the living room floor, where I stepped on it trying to find it to clean it up. (Blond wood, clear pee. Joy.) Right now Dymphna is munching on some vegetables behind me. I don't know where G'Kwan is, but I'm feeling horribly guilty for not paying closer attention.
