Cheyletiella is a genus of mites that lives on the skin surface of dogs, cats, and rabbits. For a related condition, see canine scabies.


Humans with pets infested with Cheyletiella may be bitten by the mite. Multiple red, itchy bumps develop. The classic clinical presentation is grouped itchy bumps on the abdomen and arms of a patient whose cat sits on his/her lap. Bullous lesions may occur and rarely the lesions may be widespread. Patients may be affected after sleeping where the pet sleeps. In severe cases, arthralgias and a peripheral eosinophilia have been reported.


Curing the pet cures the skin master. Topical steroids may be given.
