People are saying that some "Blue Sheep" were caught doing the impossible, per usual, in the Valley of the Cats, China recently.
In actuality they are mountain climbing Goats who climb that high to protect themselves from predators. Their feet are evolved to grapple on tiny cracks in the rock, so the rock is not perfectly lean it has abrasions.
Some people online have been saying that it's not true and the video was shot on a weird angle to make it seem like the animals were walking down a cliff face buuuut then there's this video proving it to be real.
Clever little things! I think it's super cool.
