We examined changes of epinephrine, norepinephrine, and cortisol levels in 24-h urine accompanying emotional behavior in cats such as restlessness, threat, and quiet biting attack elicited by electrical stimulation of specific sites within the hypothalamus. Although norepinephrine remained unchanged with restlessness but increased with threat, elevation of epinephrine and cortisol levels was common to restlessness and threat. No significant changes in these hormonal levels were seen with quiet biting attack and control. Therefore, it was suggested that emotional behaviors such as restlessness and threat are more closely related to emotional stress than quiet biting attack in cats.
我们检测了猫在情绪行为（如下丘脑特定部位电刺激引发的躁动、威胁和安静撕咬攻击）过程中24小时尿液中肾上腺素、去甲肾上腺素和皮质醇水平的变化。虽然去甲肾上腺素在躁动时保持不变，但在受到威胁时会增加，而肾上腺素和皮质醇水平的升高在躁动和威胁时均常见。安静撕咬攻击和对照组中这些激素水平未见明显变化。因此，提示在猫中，躁动和威胁等情绪行为比安静撕咬攻击与情绪应激的关系更为密切。
