研究了短尾狼（Lepus brachyurus）硬、软粪便的形成和再摄取的日常节律。虽然人们早就知道狐猴会吃软的粪便，但日本人也会吃大量的硬粪便。白天排出的所有粪便都以一种形式存在，首先是硬的粪便，然后是软的粪便，然后是硬的粪便，被重新摄入。兔反复从蹲姿坐直，练习进食。硬粪的进食过程包括反复的排便动作，每次都伴随着咀嚼，而软粪的进食过程只包括一次排便动作，不包括咀嚼。如果在夜间觅食时被剥夺了食物，日本人会重新摄入大部分通常被丢弃的粪便。文献证据表明，其他狐螨科也会进食坚硬的粪便。
The daily rhythms of formation and reingestion of hard and soft faeces were studied in Lepus brachyurus. Although the Leporidae have long been known to reingest soft faeces, the Japanese hare also reingests a substantial amount of hard faeces. All the faeces excreted during the daytime stay in a form, comprising first hard faeces, then soft faeces and again hard faeces, were reingested. Hares repeatedly sit straight up from the squatting position to practise reingestion. A reingestion bout for hard faeces consists of repeated faeces-taking actions each followed by mastication, whereas that for soft faeces includes only one faeces-taking action without mastication. If deprived of food during foraging at night, the Japanese hare reingested most of the faeces that were normally discarded. Evidence in literature indicates that other Leporidae also practise reingestion of hard faeces.
