A Low Rumble

Stiffness cracked away. A sharp intake rattled deep inside my throat. My claws pressed firm into the dense grey carpet. Ahead, glowing colors pulsed on the floor. I stiffened my spine, snapped my jaws wide, and emitted a resonant, guttural hiss. Nothing struck back. Lowering my snout, I cautiously crept forward and nudged the glowing mouse with the tip of my lower jaw. It slid an inch, silent and harmless. Territory secured.
