Independent animals regularly clean themselves and put their feathers, fur, and other skin coverings in working order. This activity is known as personal grooming, which is a form of hygiene. Shaking off foreign objects, such as insects, leaves, parasites, twigs, and dirt is par for the course when you are an animal.
Cats groom so often that they often suffer from hairballs because of the fur they ingest. Cats are notorious for their extensive grooming. Grooming plays a unique role in animals bonding and strengthening their social behaviors. In humans, proper grooming involves showering on a regular basis, shaving, styling your hair, and wearing clean clothes.
