We’ve all seen at least one of these videos – the Great Dane and the deer, the cat and the owl, or the sheep and the elephant (if not, you can check them out plus two more right here). These are just some of the odd animal couples that have been documented and posted on YouTube for us all to see.

Truly, it’s astounding to see different species get along so nicely – something thought so rare before.

BBC One has set out to examine these special interspecies friendships through a weekly one hour program called “Animal Odd Couples.” You can watch the full episodes here, as they are loaded.

The show follows wildlife biologist, Liz Bonin, on a worldwide journey to find out why different species become friends. A few of these adorable couples include:

• The capybara and her puppies.
• The polar bear and the huskies.
• The tiger and the bear.
• The orangutan and the dog.
• The chimp and the puma.
• And the jaguar and the dog.

In its description of the program, BBC One states, “These animals are displaying what looks like friendship, affection and even love towards one another. But what lies at the heart of these [behaviors]? Can science explain why these unusual partnerships take place? And if so, what can they teach us about how the animal kingdom really works?”

See a short clip of the show for yourself below, featuring a very loving cat cuddling not just her own kittens, but also newly adopted ducklings. Simply adorable!
