I know this is an essentially an advert but the video was so wonderful I couldn't resist! I have a book called Unlikely Friendships (and in fact there is a whole series of books) and I find myself thinking that actually it is only humans that think it is 'unlikely'.
Realistically though I guess some humans get on with each other just fine and so do a variety of different animals. Maybe these animals are the 'forward thinkers of the world' just like us vegans.
Maybe I'm over thinking it.........ah whatever; it made me smile a hell of a lot!
