Grooming behavior refers to the actions animals take to clean and maintain their bodies, often involving licking, scratching, or preening. This behavior is essential for removing dirt, parasites, and dead skin, which helps to keep the animal healthy. Many species, including cats, birds, and primates, engage in grooming as a part of their daily routine. In addition to hygiene, grooming can serve social functions. For example, in primates, grooming helps strengthen social bonds and establish hierarchies within groups. Similarly, in birds, mutual grooming can enhance relationships between mates or flock members, promoting cooperation and reducing stress.
