Why does a cat's hair grow in layers? How long does it take for a cat's hair to grow back after it is shaved?

Many people like to pet cats because they like the furry feel. The smooth cat hair is really comfortable to touch. However, if the cat's hair is not taken care of, the cat's hair will become tangled and layered. Because cats have three layers of hair, they will sometimes layer.

Why do cats have layered fur?

Cats have three layers of fur. The first layer is the outermost layer that we can see directly. It is the longest hair among the three layers and is relatively hard. It is equivalent to a protective layer that protects the skin and the inner layer of fur from external damage and prevents sunlight from directly contacting the skin.

The second layer is the awn hair, which is shorter than the first layer and longer than the third layer. It can keep warm, insulate, and is waterproof, so don't shave it easily.

The third layer is the undercoat, the shortest layer of hair. It is close to the skin and very short. Its main function is to protect the skin and keep warm.

If the cat's hair is obviously layered and the roots can even be seen, the owner should first check whether the cat's skin is normal. If it is normal, it may be that the hair is not well taken care of or it has not been bathed for a long time. In addition, this situation may also occur if the cat is too fat, fed improperly, or lacks nutrition.

How long does it take for a cat's hair to grow back after being shaved?

Generally speaking, the hair will grow back in about 3 to 4 months. If it is a long-haired cat, it will take about half a year for it to grow to the same length as before.

However, if there is no special reason, it is not recommended for the owner to shave the cat. The cat's hair can not only play a role in the cold, but also protect the cat's skin. If the cat needs to be shaved due to skin disease, the owner needs to use a pet-specific razor to shave. If the owner has never shaved before, it is recommended to shave in the direction of the hair.

Why do cats shed hair?

1. Physiological hair loss. The principle of replacement of old hair with new hair, when the hair grows to a certain extent, it will fall off and new hair will grow, which can better protect itself.

2. Shedding due to seasonal changes. When the weather is cold, cats will grow a lot of hair to keep warm. So in the summer, when it is very hot, in order to prevent heat stroke, they need to shed the hair grown in winter, mostly down.

3. Pathological hair loss. Hair loss occurs when a cat is sick, has parasites, or has skin diseases. These are more serious and require treatment. In addition, poor diet and other diseases can also cause hair loss. Therefore, you should pay attention to observation. When a cat is sick, its hair will become dull and matte, and the amount of hair loss will be large. If there is a problem, you need to seek medical attention and receive timely treatment.
