Hair pulling has been reported in humans, six different non-human primate species, mice, guineapigs, rabbits, sheep and muskox, dogs and cats. This behaviour seems to occur only in subjects who are confined in an artificial environment. It has been classified as a mental disorder in humans, as a behavioural pathology in animals. The hair is not only pulled but also, in most species, ingested. Hair pulling can be both self-directed and partner-directed, contains elements of aggression, manifests more often in females than in males, is associated with psychogenic distress, and resists treatment. Research data collected from affected animals are probably not normative, hence scientifically unreliable. The preemptive correction of husbandry deficiencies causing long-term stress may prevent the development of this bizarre behaviour in healthy subjects.
人类、六种不同的非人类灵长类动物、小鼠、豚鼠、兔子、绵羊、麝牛、狗和猫都有拔毛行为的报道。这种行为似乎只发生在被限制在人工环境中的个体身上。在人类中，它被归类为一种精神障碍，在动物中则被归类为一种行为病理学。毛发不仅被拔掉，而且在大多数物种中还会被吞食。拔毛行为既可以是自我导向的，也可以是针对同伴的，包含攻击性行为的元素，在雌性中比在雄性中更常见，与心理困扰有关，并且难以治疗。从受影响动物身上收集的研究数据可能不具有规范性，因此在科学上不可靠。对导致长期压力的饲养缺陷进行预防性纠正，可能会防止健康个体出现这种怪异行为。
