Whiskers are an important part of a cat's anatomy. They are course and wiry, and are found on their cheeks and eye brows. Cat's lose an occasional whisker much like we lose eye lashes, but they are not shed in the same manner as their fur. The roots of each whisker have lots of nerve endings, and can feel differences in air pressure. Cats use their whiskers in the dark during the hunt to help them locate objects and prey. They also help them evaluate small openings. Contrary to popular belief, their whiskers will grow back if they are cut off, but it may handicap their effectiveness in the dark.
