Friends and enemies in the animal world tend to be pretty clear-cut -- there are some species that just weren't born to get along. But as these unlikely pairs show, even Mother Nature doesn't set things in stone: Who says that orangutans and tigers, dogs and deer, cats and birds can't all be friends somehow?

From a sheep that brought a baby elephant out of a deep depression to natural enemies that snuggle down together for every nap, these 10 heart-wrenching relationships are incredible and unforgettable.
