Hibernating pocket mice (Perognathus flavus) were obtained from the Department of Veterinary Medicine, Hokkaido University, in September 1990, and attempted to rear them in National Institute of Neuroscience, NCNP. Rearing of pocket mice was possible under the general conditions used for rearing mice. As a result of random mating of 4 females to 2 males for breeding, gestation was achieved in only one pair of animals, and parturition under artificial rearing conditions was observed for the first time. The animal gave birth to 3 offspring that had no body hair. Their eyes were closed. Each of the offspring weighed about 1.0g. The mean body weight of the females was 6.5g and that of males 5.6g at 3 weeks. Weaning was possible at this age. Subsequently the animals grew rapidly; the body weight was almost equal to that of an adult animal (8.0g) at 5 weeks of age for the females and 7 weeks for the males. The gestation period was estimated to be 26 days. These findings indicate that pocket mice can be bred and reared under general laboratory conditions.
1990年9月，从北海道大学兽医学部获得了冬眠袋小鼠（Perognathus flavus），并尝试在国立精神神经医疗研究中心饲养它们。在用于饲养小鼠的一般条件下，可以饲养袋小鼠。将4只雌性与2只雄性随机交配进行繁殖，结果只有一对动物成功受孕，并首次观察到在人工饲养条件下分娩。该动物产下了3只无毛的幼崽。它们的眼睛是闭着的。每只幼崽体重约1.0克。3周时，雌性的平均体重为6.5克，雄性为5.6克。这个年龄可以断奶。随后，这些动物迅速生长；雌性在5周龄时、雄性在7周龄时体重几乎与成年动物（8.0克）相等。妊娠期估计为26天。这些发现表明，袋小鼠可以在一般实验室条件下繁殖和饲养。
