title: Feline demodicosis caused by an unnamed species.
abstract: A case of feline demodicosis is described in this report. A 13-year-old spayed female domestic short hair cat weighing 4.5 kg was being treated with cefovecin and alternately with prednisone or methylprednisolone. On further physical examination, the cat showed mild erythema and hair loss on the bridge of the nose, around the eyes, on the chin, on the side part of the breast and on the abdomen. A large number of Demodex mites were found in deep skin scrapings from the affected areas. The cat was then treated with ivermectin at 600 μg/kg administered SC daily. After 4 weeks of treatment, the cat was clinically normal with no mites detected in the skin scrapings from the face or breast areas. The mite responsible may represent a previously seen but as yet unnamed new species. This is third report that describes a case of feline demodicosis caused by a different, unnamed mite species that has different morphological characteristics to those of known Demodex mites and may represent a previously seen but as yet unnamed species.
