Feral Children

I found this compendium of feral children, which are children who grow up without any human contact. Included are many stories about children raised by animals in the wild. Of particular interest are the ones raised by wolves, apparently one of the more popular creatures to take human babies into their packs. Feral wolf children share many similar characteristics, including heightened senses and an appetite for raw meat and blood. One in particular:

Shamdeo hated the sun and sought out dark corners: he became restless after dark... he caught chickens alive and ate the whole bird, including the entrails; he was also strongly attracted to the smell of blood.
