各种报道讨论了维持老鼠的最低笼子高度为14厘米。已经提出了身高在18到22厘米之间的建议，并部分付诸实施。然而，没有关于老鼠实际使用较高笼子的量化数据。因此，使用被动红外探测器对54只大鼠在19厘米和30厘米高的笼子中直立站立以及在地板上的活动进行了评估。结果表明，保持架高度的使用呈持续递减趋势。成年动物平均每天超过24 cm高度的时间分别为13.8分钟(品系ACI)和5.2分钟(品系LEW和SPRD)，分别相当于笼底活动的8.7%和5.5%。显然，直立站立是实验大鼠行为图中不可或缺的一部分，表现出与运动活动相似的依赖紧张的昼夜节律。
Various reports have discussed a minimal cage height of 14 cm in rat maintenance. Recommendations for heights between 18 and 22 cm have been proposed and partially put into practice. However, no quantitative data exist on the actual utilisation of higher cages by rats. Thus, upright standing in 19 and 30 cm high cages as well as locomotor activity on the floor was assessed in 54 rats using passive infra-red detectors. The results showed a continuously decreasing use of cage height. On average, adult animals exceeded even a height of 24 cm for 13.8 (strain ACI) and 5.2 (strain LEW and SPRD) minutes per day respectively, corresponding to 8.7 and 5.5% respectively of the locomotor activity on the cage floor. Obviously upright standings is an integral part of the laboratory rat's ethogram showing similar strain-dependent circadian rhythms as locomotor activity.
