An Ape and Her Otter

In most mixed-species exhibits, the best you can really hope for is animals that are willing to share the same space while largely ignoring one another.  After all, that's how it usually goes in the wild - if another animal isn't a predator or prey, you're likely to simply just let it be.  Sometimes two animals of different but closely-related species will cohabit and strike up a close relationship, maybe sometimes even mating; while the former can be encouraged, providing companionship for animals, the later is generally discouraged, as it results in hybrids.

I don't think I've ever seen a video which has ever given me such strong "pet" vibes as this recently-shared video from the Kansas City Zoo and Aquarium.  I've seen mixed primate-otter exhibits before at a variety of zoos, though I've also heard a few horror stories about less-pleasant (sometimes lethally so) interactions between the animals involved.  In this video, however, it really seems that there is some mutual affection going on here.  

You can almost imagine a gibbon sitting on the couch with a book and a glass of wine, absent-mindedly petting the otter that's curled up next to her, perhaps gnawing on a fish-flavored chew toy.
