Cardboard Box Tunnel
A narrow gap behind the sofa drew me in, smelling richly of dusty carpet and dried paper. Right in the crevice, an open cardboard shipping box lay tipped on its side! With a sharp, excited yip, I scrambled headfirst inside to explore the dark tunnel. The bottom flap bent under my paws with a loud, crinkly snap, and my nose bumped against a tight fold of brown packing paper. I tugged hard at the crinkled sheet, dragging a loose strip halfway out to claim my new paper cave!
