We often see cats washing their faces with their paws, and we think it's because they're clean. But there are reasons why cats like to wash their faces, and it's not just because they're clean. Here are some reasons why cats like to wash their faces. 
I. Reasons why cats wash their faces
First, washing their faces cleanses their skin and restores the sensitivity of their whiskers, a very important sensory organ. Cats usually wash their faces very diligently, and their actions are quite amusing.
Secondly, because cats use their paws to scratch the sensitive areas of the facial nerves, this also has certain health benefits. Simply put, it's like the cat is massaging its own face, which is very helpful in maintaining the sensitivity of its facial nerves.
Thirdly, another reason cats like to wash their faces is because they are clean animals. This is related to their long-term life in the wild. In the wild, to avoid being tracked by prey, cats must clean their bodies regularly, keeping them clean and preventing them from emitting a scent that would attract nearby predators. Washing their faces serves the same purpose, and maintaining their sensory sensitivity is crucial for a cat's safety in the wild and for escaping danger.
Actually, there's another important reason why cats love to wash their faces. Later research on cats discovered that when cats lick their faces with their front paws, they apply their saliva. This saliva dissolves vitamin D in the cat's fur. Then, they ingest the vitamin-dissolved saliva from their paws. Due to the stimulation of ultraviolet rays from sunlight, the cat's body produces vitamin D. So, cats lick their fur to supplement their vitamin D intake.
II. Neglected Cleaning of Cats
Many pet owners are unaware of the significant impact their pets' health has on their lives. Thorough cleaning plays a crucial role. Imagine someone's pet has skin diseases all over its body, is infested with fleas and ticks, and has foul-smelling ears. Living together like this every day creates a deteriorating environment, and the person living with the pet will also become unwell and infected. Based on common areas that pet owners often overlook, the following points are offered for reference:
1. Ear hair: This is an area many pet owners neglect. If not cleaned properly, water can easily accumulate in the ears after bathing, causing inflammation and odor, which is troublesome for both the pet and the owner. Also, do not insert cotton swabs into the ear canal, as this may push the dirt deeper and have the opposite effect.
2. Nail length: The general principle is to cut the nails so as not to cut into blood vessels and cause bleeding. Many dogs hate nail trimming because they are afraid of pain when blood vessels are cut, which can lead to problems later on.
3. Paw fur: If the fur on the bottom of a pet's paws is not shaved, the pet may slip and fall when running indoors. This is something that many pet owners do not often pay attention to.
4. Belly hair: helps keep the abdomen clean and hygienic.
5. Hair around the anus: helps prevent excrement from sticking.
Cat grooming is a frequently discussed topic, but there are still some aspects that we overlook. Prolonged neglect of grooming can lead to bacterial infections in cats, which can also harm the health of their owners. Therefore, thorough grooming of cats is very important.
