Reasons for cat shedding:
1. Before summer arrives, cats will change their long fur to short fur to cool off, and before winter arrives, they will change their short fur to long fur to keep warm. This is seasonal shedding.
2. Cats that eat poor-quality cat food for a long time will suffer from malnutrition or excessive salt intake, which can lead to large-scale hair loss.
3. When a cat has ringworm, its skin will start to lose a lot of hair, and the skin in the hair loss area will become red. 
Solutions for cat shedding:
1. Regularly brush your cat's fur. Brushing not only collects loose fur but also promotes blood circulation, which is beneficial for fur growth.
2. Letting your cat bask in the sun can also help alleviate shedding. Sunlight can effectively kill parasites, mites, fungi, fleas, and other parasites that live on cats. It can also kill bacteria on the surface of the cat's skin and in its fur, reducing skin diseases and benefiting its coat.
3. You can also supplement your cat's diet with amino acids, which can promote hair growth.
4. If the hair loss is caused by a skin condition, you need to go to the hospital to cooperate with the doctor to treat the skin and solve the hair loss problem.
