“Heaven help us,” is a phrase often uttered by parents when their kids find a loyal partner in crime. Sometimes it can even happen as early as the first day of school. The need for friendship and companionship is experienced not just by humans, but by many animals in nature.

One such example is the story of Kumbali and Kago, a cheetah and a labrador mix puppy who have become like brothers while being reared at the Metro Richmond Zoo in Richmond, Virginia. As they explain, a symbiotic relationship like this has almost zero probability in the wild, but it’s simply too cute and heartwarming not to share.
