Abnormal maternal behaviour has been reported in cats, but is generally not included among the causes of alopecia in kittens. A litter of four kittens, 2 months old, was referred for evaluation of facial alopecia of differing severity. The 2-year-old queen was unaffected. Dermatological examination of the kittens did not find any infectious cause. Trichograms showed broken hair shafts with longitudinal splitting. Congenital alopecia was unlikely based on the clinical presentation. A behavioural consultation revealed abnormal grooming behaviour by the mother, who chewed and removed the hair from the kittens. The kittens were separated from the queen and alopecia resolved within a few weeks.
To the authors' knowledge, this is the first report of alopecia caused by abnormal maternal licking behaviour. Abnormal maternal behaviour should be considered in cases of alopecia affecting a litter of kittens, when infectious and congenital causes have been ruled out.
猫出现异常母性行为已有报道,但通常不被列为小猫脱发的原因之一。一窝4只2月龄的小猫因不同程度的面部脱发前来接受评估。这只2岁的母猫未受影响。对小猫进行的皮肤科检查未发现任何感染性病因。毛发检查显示毛干断裂并纵向劈裂。根据临床表现,先天性脱发不太可能。行为咨询发现母猫存在异常梳理行为,它会啃咬并拔掉小猫的毛发。小猫与母猫分开后,脱发在几周内得到缓解。
据作者所知,这是首例由异常母舔行为导致脱发的报告。在排除感染性和先天性病因后,对于一窝小猫出现脱发的情况,应考虑异常母性行为。
