Cat whiskers do far more than allow a cat to measure the width of a space. They provide a form of sight to a cat by acting as air current detectors, which is particularly useful in the dark when eyes are less useful. The sensitivity comes from the nerves at the base of the whiskers. The whiskers are embedded in the upper lip of the cat 3 times deeper than the other hairs. At the base of the hair is a mass of nerve endings, which transmit to the brain any minute impact on the end of the whisker, be it actual contact with an object or an air current. The signal is transmitted via the fifth cranial nerve to a part of the cat’s brain that is similar the a human’s visual cortex. The part of the human brain that process light signals from the eyes.
