I had no idea this was a real thing, but apparently babies can be raised by wolves, goats, and in this one case monkeys.  This article talks about 6 people who when abandoned by humans, were adopted by other species.  It seems horrible for the kids involved, but in truth they didn’t know any different.  It’s amazing how mothers are mothers, no matter if they are people, goats, rats, monkeys, dogs, etc.  It is really touching, to me at least, to see that love and caring are truly universal.  While most humans act above nature, the other 99.99% of the life on this planet proves them wrong every time.
