A Shiny Metal Grid

Down by the curb, a dark iron grate was set right into the street, casting neat checkerboard shadows below! I bounded forward with a flying leap, dropping onto my plush knees right at the edge. Sticking my long arms straight down through the wide parallel slots, my white mittens dangled into the cool, mysterious underworld. A smooth, round pebble was wedged near the lip. With a gentle tap-tap of my fingers, I nudged the pebble until it rolled free and dropped—plink! A sharp, echoing ring bounced up from the deep hollow. Thrilled by the secret song, my whole chest vibrated with an excited, rumbly purr.
