We know, we know, it’s totally irrational to think that the world is going to end on Dec. 21. But then you see something like a kangaroo giving a dog a belly rub, and you have to wonder just a little bit if the world is coming to an end.

What’s with all these species getting along like this is Noah’s Ark or something? Why is this cat nursing a bunch of hedgehogs? [Warning: there's some sort of graphic kitty nipple action in the below video.]

What’s next? Lions laying with lambs? DOGS AND CATS LIVING TOGETHER?
