捕食者气味是具有高度行为学相关性的非侵入性自然应激源。动物每天都面临着不同强度的应激源的挑战，对于它们的生存来说，应对广泛的威胁是必不可少的。以家猫(Felis Catus)的粪便为实验材料，观察了布氏田鼠(Lasiopoomys Brandtii)暴露不同时间后的行为和激素反应及下丘脑内侧核-fosmRNA水平的变化。100只田鼠在防御撤退装置中进行了测试。田鼠对新收集的猫粪表现出厌恶，表现为与飞行相关的行为水平高，冰冻行为增加，与旧粪便相比饲养更警惕。当田鼠接触新鲜猫粪时，血清促肾上腺皮质激素和皮质酮水平显著升高。在接触新鲜猫粪的个体中，下丘脑内侧区的Fc-fosmRNA水平最高。所有这些行为、内分泌和c-fos-mR-NA反应在接受较老猫粪的田鼠时都较低。我们得出的结论是，这些反应取决于猫粪便的挥发性化学成分，而不是它们的物理特性，这就是为什么猫对储存时间较长的粪便的反应较低。
Predator odors are non-intrusive natural stressors of high ethological relevance. Animals are daily challenged with stressors of varying intensity and it is essential for their survival to respond to a wide range of threats. Behavioral and hormonal responses and changes in the level of medial hypothalamicc-fosmRNA were examined in Brandt's voles (Lasiopodomys brandtii) exposed to the feces of a domestic cat (Felis catus) stored for different periods. One hundred voles were tested in the defensive withdrawal apparatus. The voles showed an aversion to freshly collected cat feces, indicated by high levels of flight-related behaviors, increased freezing behavior, and more vigilant rearing compared to old feces. The serum levels of adrenocorticotropic hormone and corticosterone significantly increased when the voles were exposed to fresh cat feces. The level ofc-fosmRNA in the medial hypothalamic region was highest in the individuals exposed to fresh cat feces. All of these behavioral, endocrine andc-fos-mRNA responses were lower when voles were subjected to older cat feces. We conclude that these responses depend on volatile chemical constituents of cat feces rather than their physical characteristics and that this accounts for the lower responses to feces stored for longer periods.
