Slip of the tongue


Licking is a common way for animals to clean themselves. In mammals, licking helps keep the fur clean and untangled. The tongues of many mammals have a rough upper surface that acts like a brush when the animal licks its fur. Cats use licking both to clean, and to show affection among themselves or to humans typically licking their faces.
