The causation of two scent-marking behaviour patterns in female hamsters (Mesocricetus auratus).
Social, olfactory, and oestrous cycle influences on the frequency of flank-marking and vaginal marking were studied in female hamsters. Vaginal marking was more frequent in the presence of males or their odours than females or their odours. Vaginal marking frequency was greatest the day before oestrus (day 4), intermediate on days 2 and 3, and zero on the oestrous day. The probable sexual advertisement functions of vaginal marking were discussed. In contrast, flank-marking by females was stimulated more by other female odours than by male odours. The frequency of flank-marking was elevated by agonistic encounters and was reduced by sexual encounters. Flank-marking seems to have functions related to functions of aggression among hamsters.
