What are whiskers? Whiskers are thick, stiff, hair-like projections and are called ‘vibrissae’ because they vibrate when a current of air passes over them.
How do whiskers work? The base of each whisker is connected under the skin to a network of tiny nerves that transmit signals to the brain in nano-seconds. The whisker vibrates in response to a mere current of air and/or touch. The nerves notify the brain of the vibration. Whiskers, responding to air currents and touch, guide your cat through the maze of objects in their 'jungle' inside and outside your home.
