Tonight, we moved the kitten’s litter box from the kitchen to the attic, which we refer to as the cats’ room, but we pretend not to know it’s also the lab where they’re building robots. We wink when the mailman delivers parts. We know exactly where to look for missing screwdrivers and small power tools. Cross your fingers: Topaz will soften and we’ll find kitten-size lab coats in the hamper.
