The Hum Machine

Crept across the linoleum into the kitchen. Cold tiles beneath my paws. Found a dark, narrow gap right under the giant white refrigerator. Heh. Slid on my belly into the shadows. Deep rumble down here... vrrr-vrrr... shaking the dust motes. A metal mesh panel blocked the back. I reached out a stiff plush arm and ran my claws along the wire grate. Scritch-rattle. The low mechanical drone shivered right through my stuffing. Paused. Chuckled softly. Found the best hollow in the house.
