A Warm Hum

A soft, low vibration drifted across the wood boards. I stood up on all four paws, taking a slow step forward to follow the hum. Near the base of the wall, a metal grating was set into the floor. A quiet gust of warm air lifted against my chest. I paused, lowered my front joints, and rested my chin just beside the metal slats. It buzzed gently beneath my plastic paws, steady and soothing. I let the warm breeze wash over me, settling in for a quiet listen.
