Tiger and piglets

This mother tiger is raising piglets:


The photo is genuine, and despite gags about it ending in tears when momma gets a little peckish, the tiger herself was raised by a pig and is very unlikely to turn on "her" babies. It's a good example of animal psychology: the tiger isn't likely to be fooled by the tiger skins on the piglets, especially once they skins have been washed a few times and lose any residual tiger scent, but it shows that some animals learn what to consider prey and what not to.

Although the above situation was artificial in the sense that human beings manipulated the tiger to raise the piglets, such situations sometime occur in the wild. True stories (and some not-so-true) of human children being raised by wolves are common. Less common but still well-documented include cases of predators raising babies of their usual prey species, for example the well-documented case of a lioness in Kenya that tried to raise no fewer than three baby antelopes.
