Old Woman Zhang, resident under Feicheng County in Jiningfu, her husband having died young, lived together with her son Zhang Lü’er. By day she watched over baskets of spun hemp, by night she transformed into a raccoon dog, going everywhere to steal and eat small children from people’s homes. Those lost numbered eighteen or nineteen. One day she also turned into a white donkey, eating someone’s wheat seedlings, but was caught by the owner of the wheat, chained by the neck and dragged to a millstone, where she was given a severe thrashing. Finally released she was able to return, moaning and groaning, and lie down, at which her son questioned her, and she related all and was beaten to death by the people; this is truly something to marvel at.
 This character is presently used to refer to the tanuki, a prominent trickster animal in Japanese folk culture, but seems more likely to refer to a cat of some sort. On the tanuki, see Adrian Burton, “The Transformations of Tanuki-San” Frontiers in Ecology and the Environment 10 (2012): 224. Present-day populations seem expected to be broadly omnivorous, their living prey limited to smaller animals. Research on the mandibles of extinct raccoon dog subspecies suggests that their diet may have varied greatly in the past (but the researchers don’t mention human babies). See Masakazu Asahara and Masanaru Takai, “Estimation of Diet in Extinct Raccoon Dog Species by the Molar Ratio Method”, Acta Zoologica (Stockholm) 98 (2017): 292-99. As noted by by Barend Ter Haar, the story is also related to the child-eating elderly female cannibal or were-animal ‘Auntie Old Tiger’ story, a tale comparable to Hansel and Gretel.
