It is said that cats are easy to keep, because they do not need as much activity as dogs, nor do they need to worry about going to the toilet for them. The most important thing is to lick your feet with your tongue to wash your face. The following three aspects tell you why cats love to wash their faces.

First, washing the cat's face can cleanse the skin and restore the sensitivity of the very important tactile organ of the beard. Cats are usually very serious when they wash their faces, and of course their movements look very interesting.

Second, it is precisely because cats use their small claws to scratch the sensitive areas of the facial nerve, so it also has a certain health care effect. Simply put, the cat seems to be massaging its own face, which is very helpful for its facial nerves and maintaining sensory sensitivity.

Third. Another reason why cats love to wash their faces is because they are animals that love cleanliness. This is related to the long-term wild life of cats. To survive in the wild, in order to prevent being stalked by prey, cats must clean their bodies in time to keep their bodies clean and not emit odor to attract ferocious prey not far away. The same goes for washing the face, and maintaining sensory sensitivity is critical for cats to live safely in the wild and avoid danger.

In fact, there is another important reason why cats love to wash their faces. Later studies on cats found that cats dipped their saliva with their front feet on the face, which could dissolve the vitamin D in the cat's fur, and then they re-eat the vitamin-dissolving saliva from their feet into their mouths. The ultraviolet rays in the cat stimulate the cat's body to produce vitamin D, so the cat licks the fur to supplement vitamin D.
