Cats have a special upper lip structure, and the lips are composed of two parts. The first part is the laryngeal process located in the center of the upper lip, which connects the teeth with the lower lip and is responsible for controlling and regulating the airflow in the cat's mouth. The second part is the upper lip on both sides, which is elastic and plays an important role when cats eat and wash their faces.

The upper lip structure of cats can effectively help them catch food, especially for fast-moving prey, such as mice and birds. When a cat is chasing prey, its upper lip will vibrate at high speed, forming a "capture" airflow, which can enhance the cat's olfactory perception and auditory localization ability and play an important role in helping it hunt.

In addition, the upper lip structure of cats can also help them clean themselves. When a cat licks her face, her upper lip will bend into a V-shape, which can clean her face more efficiently and remove impurities such as dust and dirt.

Generally speaking, the upper lip structure of cats is very special and useful, which can not only help them catch prey, but also help them clean themselves. Therefore, when taking care of the cat, we should pay attention to its oral hygiene and food intake to ensure that its upper lip structure works normally.
