Feline demodicosis: a consideration in the itchy or overgrooming cat

In cats, three species of demodex mites have been identified as causes of demodicosis, which may manifest as pruritus, miliary dermatitis and/or self-induced alopecia. The condition has been recognized in various countries but does seem to show regional preferences.

Diagnosis of feline demodicosis can be a challenge as mites are not always readily found within scrapings of the skin examined microscopically. One or more species of demodex mite may be involved in an infestation. Furthermore, the condition can be difficult to treat effectively.

This review is intended as a clinical update for veterinary surgeons in practice who rarely encounter demodicosis.
