Pairs of hamsters were housed in large enclosures that contained separate male and female living areas and observed over the 4-day estrous cycle and after ovariectomy. Agonistic elements exhibited frequently by females included on-back, boxing, lateral posturing, and biting, whereas males engaged frequently in boxing and on-back patterns of behavior. Furthermore, on-back and boxing by females were significantly higher on estrus than on any other day of the estrous cycle. Agonistic acts performed after ovariectomy did not differ in occurrence from those shown by animals on diestrus and proestrus. Vaginal marking increased during diestrus and attained a peak 24 hr prior to sexual receptivity. Both vaginal marking and mating occurred more frequently in the female's than male's home area suggesting that vaginal marking and mating occurred serve to attract males to the nest of females. Males also organized their marking patterns by location as shown by more flank marking in their own than their partner's area, albeit the significance for this difference in location is not known. The results demonstrate that when heterosexual pairs of hamsters are tested in large and partially familiar habitats, a wide range of behavior is exhibited and organized in a manner that is not observed in small and unfamiliar cages.
将成对的仓鼠饲养在大型围栏中，围栏内设有单独的雄性和雌性生活区，并在4天的发情周期以及卵巢切除术后进行观察。雌性仓鼠频繁表现出的攻击行为包括仰卧、拳击、侧向姿势和撕咬，而雄性仓鼠则频繁出现拳击和仰卧行为模式。此外，雌性仓鼠在发情期的仰卧和拳击行为明显高于发情周期的其他任何一天。卵巢切除术后的攻击行为发生率与处于间情期和发情前期的动物所表现的行为没有差异。阴道标记在间情期增加，并在性接受前24小时达到峰值。阴道标记和交配在雌性仓鼠的领地比在雄性仓鼠的领地更频繁地发生，这表明阴道标记和交配起到了吸引雄性仓鼠到雌性仓鼠巢穴的作用。雄性仓鼠也会根据位置来组织它们的标记模式，比如在自己的领地比在伴侣的领地有更多的胁腹标记，尽管这种位置差异的意义尚不清楚。结果表明，当在大型且部分熟悉的栖息地对异性仓鼠对进行测试时，会表现出广泛的行为，并以一种在小型且不熟悉的笼子中未观察到的方式进行组织。
