Touch is one of the five senses through which animals interpret the world around them. (The other senses are smell, taste, sight, and hearing.) While the organs of the other senses are located primarily in a single area (such as sight in the eyes and taste in the tongue), the sensation of touch can be experienced anywhere on the body, from the top of the head to the tips of the toes.

Without the sense of touch, animals would not be able to recognize pain, which would greatly decrease their chances for survival. Research also has shown that touch is an important factor in child development, persuasion, healing, and reducing anxiety and tension.
