1. The deer and the goose

For weeks, the deer stood watch over a nesting Canada goose in a cemetery in Buffalo, N.Y., positioning itself between the goose and any cars or people passing by. Once the ducklings hatched, the deer dutifully looked after them by chasing off crows.

2. The tiger and the piglets

Don’t let the costumes fool you: Those are real live piglets hanging out on the tiger’s back. According to Buzzfeed, the duo is being raised by the tiger, who was (wait for it) raised by pigs. The circle of life, indeed!

3. The dog and the elephant

Bubbles and Bella share a love of the water — and of each other.

4. The orangutan and the dog

It’s not your everyday adoption story, but it seems to have worked out well for the entire family.

5. The baby elephant and the sheep

Not all friendships start off on the right foot. But as this story demonstrates, that doesn’t mean they can’t grow into something wonderful.
