Russian Blue Cat

　　Folliculitis is not a big problem, and the treatment method is actually very simple. Just use a strongly alkaline detergent to clean it. You can wash the cat's tail with laundry soap (only if the tail's skin is intact).

　　Locations where folliculitis has occurred

　　Head: distributed around the chin and lip edges, appearing as small black coal-like particles.

　　Abdomen: small black coal-like particles appear around the abdomen and nipples.

　　Tail: on the dorsal side of the tail, extending from the base to about two-thirds of its length, the fur is always oily and dirty-looking.
