Etiology: Barbering in mice, depending on their genotype, is a complex behavior. Barbering most often occurs in female mice and can be attributed to dominant behavior, sexual over-grooming, maternal barbering in lactating mice, and stress-evoked barbering .
Incidence: The incidence of barbering is common.
Clinical signs: The hair over the nasal and orbital regions or the dorsal cervical area is most often barbered. The exposed skin is intact and normal in appearance.
