在三种类型的挪威大鼠（褐家鼠）：野生（WNRs），国内（DNRs），和白化病实验室Wistar（AWRs）的行为反应的气味的啮齿动物（家猫（猫卡图斯），黄鼠狼（Mustela sibirica），欧亚獾（Meles meles）），一个非捕食性哺乳动物（兔（Lepus capensis）），和蒸馏水（对照）进行了评估。将大鼠单独带到由隐藏箱和测试竞技场组成的测试装置中。记录每次试验中的行为活动，包括隐藏、外出、接近和进食行为，持续3 h。结果表明，WNR、DNR和AWR均表现出对捕食者气味的厌恶，在隐藏箱中隐藏的时间更长，接近和取食行为的频率以及摄食量均显著低于对照组。我们的研究结果表明，DNR和AWR的反应是“内置的”或先天的性质，因为他们从来没有经历过的气味测试捕食者。此外，3种大鼠均能区分捕食者和非捕食者气味，但WNR的区分能力最强，能区分同域和异域捕食者; AWR的区分能力最弱，在藏箱中的时间最长。五个气味暴露组之间的隐藏和接近行为没有显著差异。此外，三种类型的大鼠对对照组（蒸馏水）的反应显著不同。这表明圈养时间的持续时间在塑造大鼠对不同捕食者气味的反应方面发挥着重要作用。
Behavioral responses to the odors of three predators of rodents (domestic cat (Felis catus), weasel (Mustela sibirica), Eurasian badger (Meles meles)), one non-predator mammal (rabbit (Lepus capensis)), and distilled water (control) were assessed in three types of Norway rats(Rattus norvegicus): wild (WNRs), domestic (DNRs), and albino laboratory Wistar (AWRs). Rats were taken individually to a testing apparatus consisting of a hide box and a testing arena. The behavioral activities, including concealing, heading out, approaching, and feeding behaviors in each trial were videotaped for 3 h. Results revealed that WNRs, DNRs, and AWRs all showed an aversion to the predator odors by spending more time concealing in the hide box: frequencies of approaching and feeding behaviors, as well as the amount of food intake were significantly lower than control group. Our results suggest that the response of DNRs and AWRs were “built-in” or innate in nature as they had never experienced the odors of the tested predators. Moreover, all three types of rats can distinguish between predator and non-predator odors, but the ability of WNRs was the highest, which can distinguish between sympatric and allopatric predators, while the ability of AWRs was the lowest, which spent most time in the hide box. The concealing and approaching behaviors were no significantly different among the five odor exposure groups. Also, the reactions of the three types of rats toward the control group (distilled water) significantly differ. This suggests that the duration of time spent in captivity plays an important role in shaping the response of rats to different predator odors.
