A photo taken from the perspective of a person descending some grey carpeted stairs. One grey cat is in the foreground, ready to descend the stairs along with the photographer to provide a moving obstacle. Two more grey cats are lounging on consecutive steps toward the bottom of the stairs (partially within a narrow patch of afternoon sunlight), fully blocking them from being stepped on. A fourth cat is peeking around the edge of the stairs on the floor below, ready to jump in if the other three cats provide an insufficient challenge.
