Cats groom themselves using their rough tongues, which are covered in tiny, backward-facing barbs called papillae. These barbs act like a brush, allowing cats to groom their fur and remove dirt and debris. Cats also use their saliva to keep their fur clean and healthy.
Grooming is an important behavior for cats, as it helps to keep their fur clean and healthy, as well as removing parasites and debris from their fur. Grooming is also a way for cats to bond with one another, as it is a form of social grooming.
