There are two reasons why small black spots appear on cats’ skin. One is that cats suffer from folliculitis. This is caused by excessive secretion of hormones in the cat's body, which causes the hair follicle secretions to increase and then accumulate. As a result, when the cat's hair is peeled off, the cat's skin will be seen with small black spots like cinders. At this time, antibacterial and anti-inflammatory sprays can be used for treatment. The second is that the cat has parasites. This is usually caused by the owner not deworming the cat for too long or the cat's environment has fleas, and the small black spots on the cat are the excrement of these fleas.
Once the above situations occur, it also means that the owner needs to deworm the cat internally and externally.
