Through the Cat Flap

Too many runs on indoor carpet. Time to expand the field! Marched all the way down the sunny hallway straight toward the back door. Huge barrier? No problem. Spotted a low plastic swing door at bottom level. Pushed forward hard with my left shoulder while keeping the ball tucked safe. The clear flap creaked, tilted open, and let in a big gust of cool yard air. Cleared the tunnel into the real open world!
