Usually, cheetahs are born in litters of three to five, but when this cheetah's mother abandoned it to grow up alone, zoo staff decided it needed a friend.

So, staff at the San Diego Zoo brought in a dog. The dog, Raina, and the cheetah cub, Ruuxa, have become BFFs! They play and nap together and, most importantly, are the cutest friends!

Hopefully they're friends forever!
