There may be three reasons why there are small black spots in the hair of cats:

1. Dust and dirt can be wiped clean by the owner with a wet towel.

2. The owner can wipe the feces of parasites with a wet tissue, and these small black spots will turn red. At this time, the owner will deworm the cat.

3. Cat ringworm. Cats suffering from cat ringworm will also have small black spots like this, and there will also be gray and white scurf.

Tips:

Ringworm is a common skin disease in cats. Cats suffering from ringworm will have patches of ringworm on their bodies, with gray patches on them. The cat's hair will also become rough due to dandruff, and the hair will fall out in bunches. When a cat suffers from ringworm, the owner should isolate it immediately to prevent it from being transmitted to other animals.
