蜷缩，或集群行为，开始在垃圾的情况下，并持续整个成年生活的大鼠（褐家鼠）。在幼崽中，就像在成年人中一样，这种行为提供了减少热量损失的代谢重要手段。在标准化测试情况下，通过使用长期延时视频观察，研究了引起、指导和维持发育中的幼鼠（5-20日龄）蜷缩的感官刺激。所有的幼崽都和一个不能动的兄弟挤在一起。一圈温暖的管子也会引起蜷缩，但其他非热的线索也会引起蜷缩，因为一只死去的环境温度的小狗就足以刺激这种行为。通过鼻内输注硫酸锌中断正常嗅觉输入干扰了接触的维持。两种触觉刺激，垂直轮廓和毛茸茸的舒适线索，以及光反应参与了调解的蜷缩。蜷缩在altricial大鼠是在多感官控制下，虽然幼崽蜷缩使用的线索的数量似乎随着年龄的增长而增加。
Huddling, or clumping behavior, begins in the litter situation and persists throughout the adult life of the rat (Rattus norvegicus). In pups, as in adults, the behavior provides a metabolically important means of reducing heat loss. The sensory stimuli that elicit, direct and maintain huddling in developing rat pups (5-20 days of age) were studied in a standardized testing situation by using long-term time-lapse video observations. All pups huddled with a single immobile sibling. A loop of warm tubing also elicited huddling but other, nonthermal cues can elicit huddling, since a dead, ambient-temperature pup was a sufficient stimulus for the behavior. Disruption of normal olfactory input by intranasal infusion of zinc sulfate interfered with the maintenance of contact. Two kinds of tactile stimulus, vertical contours and furry comfort cues, as well as photic responses participated in the mediation of huddling. Huddling in the altricial rat is under multisensory control, although the number of cues used by pups for huddling appears to increase with age.
