Abstract
Cat fur mites (Lynxacarus radovskyi) were found on a domestic cat with alopecia and pruritus mainly living outside in Nago-city, Okinawa, Japan. The infected cat was treated with a single administration of topical spot-on typed fipronil/(S)-methoprene and daily oral administrations of doramectin. This cat indicated no skin problems after these treatments. Our case report suggests that L. radovskyi is one of the ectoparasites that might be encountered in clinical practice in subtropical regions, such as Okinawa, in Japan.
