What is the purpose of the sensory hairs around the mouth and neck of a cat?

The sensory hairs, or vibrissae, around a cat's mouth and neck serve as specialized touch receptors that help the cat navigate its environment. These whiskers are highly sensitive to tactile stimuli, allowing cats to detect nearby objects and assess their surroundings, especially in low-light conditions. Additionally, they aid in measuring the width of openings, helping cats determine whether they can fit through tight spaces. Overall, these sensory hairs enhance a cat's spatial awareness and hunting abilities.
