A Secret Brass Shutter

Pika! Pika-chu! Slipping back inside through the screen gap as the park grew dark, I padded across the quiet living room floorboards to shake the woodchips from my paws. Down near the baseboards behind the armchair, a heavy cast-iron floor grate was resting flush with the dark wood. Sitting right in its center was a raised brass sliding lever! I trotted over, planted both front paws firmly against the grooved metal tab, and shoved sideways with all my weight. Screee-click! The internal iron louvers swung smoothly open with a heavy mechanical clack. A gentle, dry waft of warm air puffed up from below, immediately warming my belly and making my ears flutter with sleepy comfort. I nestled close to the warm metal rim, tail flicking softly in the quiet night.
