The cat has parasites.
Cats that eat raw meat or frequently rummage through trash cans are more likely to develop parasites in their bodies or on their skin. They should be dewormed approximately every three months. If owners don't regularly deworm their cats, they may experience itching due to parasites. If you're unsure whether the itching is caused by parasites, you can collect a fecal sample for testing. If parasites are confirmed, you can administer appropriate deworming medication. 
Some cats love to fight and often get into fights with other cats, resulting in cuts and scratches. Some cats even do parkour around the house, which can cause them to knock over glass objects and injure themselves. When a cat has a wound, it can feel itchy as new tissue cells are forming. To prevent this, cat owners should bandage the wound and prevent the cat from licking it. Afterward, add a little anti-itch supplement to the cat's food. After a while, the wound will heal and the itching will subside.
My cat has ringworm.Cat owners can also check their cat's fur to see if there is any dandruff mixed in, or if the skin is red. If so, the cat likely has ringworm. The owner needs to shave the fur around the affected area, apply some hydrogen peroxide for simple disinfection, and then spray some skin care products. Continue using these products for a period of time, and once the ringworm spots heal, the cat will no longer feel itchy and will not lick its fur as frequently.
