Cheyletiellosis is a mild, short-term skin inflammation caused by mites that feed on skin cells. Cheyletiella is spread through contact with infested animals. Pets such as rabbits and adult cats may not show signs of infestation. However, affected kittens may have patches of scaly skin with dandruff.
The most common symptoms of cheyletiellosis in people include itching, redness, and raised bumps on areas of the skin that touched the infested animal. Cheyletiellosis in people generally resolves on its own.
