A Rolling Surprise

I marched out from my cozy sleeping spot and found something round sitting right on the bare floor! It was a shiny green tennis ball, perfectly still. I tapped it with one front paw, and whoosh—it rolled away fast! I bounded straight after it, skidding slightly across the slick boards. When it bumped softly against the wall baseboard, it bounced right back toward my nose. I pressed both paws down to trap it, proud to catch the runaway green sphere!
