The reasons why cats shed a lot of hair:
1. If a cat is malnourished and lacks enough protein or vitamins, it will continue to shed hair. It is necessary to feed the cat a variety of foods. Ensure balanced nutritional intake.

2. Cats will shed a lot of hair during the shedding season, which is normal. The owner only needs to clean up the fallen hair in time.
3. When the cat reaches the estrus period, the hormone secretion in the body will be imbalanced, and a large amount of hair loss will occur. You can wait until the estrus period is over before taking the cat to be sterilized.

4. If the cat is infected with a skin disease, it will also lose hair. You need to take the cat to the pet hospital for examination and treatment in time.
5. If your cat eats food with too much salt, it will increase the burden on the kidneys and cause hair loss. You should avoid giving your cat food that contains salt.
