Infestation of Lynxacarus radovskyi (Lynxacarosis) on cats is usually asymptomatic - most cats are presented with a dull, dry, dishevelled coat, with easily epilated hairs. The physical presence of the mite gives the coat a "peppered" appearance, and previous reports have described some cats developing pruritus and alopecia.
To describe the clinical signs of Lynxacarus radovskyi associated self-induced alopecia.
Eleven client-owned, indoor and naturally infested cats.
Cats with the primary complaint of pruritus and alopecia with sole infestation of Lynxacarus radovskyi, were included in this case series. Their age, sex, breed and clinical presentation were recorded. Cats were treated with selamectin twice, with a 14 day interval, followed by monthly maintenance therapy.
Self-induced alopecia was found on the perianal (10 of 11), caudal-lateral thighs (eight of 11), sacral-tail base region, abdomen (each seven of 11), on the flanks (five of 11) and dorsal-lumbar (four of 11) areas. There were no eosinophilic dermatitis lesions nor head and neck pruritus in any cat.
Lynxacarus radovskyi infested cats can have lesions which are strikingly similar to flea allergic dermatitis with lesions most commonly found on the perianal area.
猫感染拉多夫斯基林螨（林螨病）通常无症状——大多数猫表现为被毛 dull、干燥、杂乱，毛发易脱落。螨的实际存在使被毛呈现“胡椒状”外观，先前的报告描述了一些猫出现瘙痒和脱毛。
描述拉多夫斯基林螨相关的自我诱导性脱毛的临床症状。
11只客户拥有的室内自然感染的猫。
以瘙痒和脱毛为主要主诉且仅感染拉多夫斯基林螨的猫被纳入本病例系列。记录它们的年龄、性别、品种和临床表现。猫用塞拉菌素治疗两次，间隔14天，随后进行每月一次的维持治疗。
在肛周（11只中的10只）、尾外侧大腿（11只中的8只）、骶尾部基部区域、腹部（11只中的每处7只）、胁腹（11只中的5只）和背腰部（11只中的4只）区域发现自我诱导性脱毛。任何猫均无嗜酸性皮炎病变，也无头颈部瘙痒。
感染拉多夫斯基林螨的猫可能出现与跳蚤过敏性皮炎极为相似的病变，病变最常见于肛周区域。
