Item on YouTube: a video, age unknown, of three adult male lions having a leisurely, perfectly egalitarian 3-way:

Astounding both for its mutuality and for its cordial equality.  One might have thought that one or the other of these naturally authoritarian beasts would have wanted to hog all the attention, or, perhaps, have grown jealous of one of the others--but no, I've never seen, except in the 3-ways of male dolphins, and of men, so perfectly gentlemanly and fraternal a sharing and enjoyment of their own and one another's bodies.

And speaking of YouTube revelations there is another video of a full-grown lioness have carefully isolated and cut off from his herd a very young wildebeest, whom she has only to lay under her massive paw and deliver the mortal neck-bite to--and the youngster charges her, and does so repeatedly, while her deflection of his charge grows ever gentler and more maternal, till she is just holding him down and licking him like one of her own cubs, and eventually simply lets the brave little fellow go.  As only a Christian could fail to understand:  Kids is kids.
