Two long-haired cats are perched on a white shelf attached to a wall, with a wooden hexagonal cat house above them. The cat on the left, with a grey and white coat, hangs upside down from the shelf, its paws gripping the edge, while the cat on the right, with a grey coat, sits upright beside it; the hanging cat then pulls itself up and over the shelf, disappearing from view.
