Having a best friend is amazing, especially one that you’re lucky enough to grow up with! and whilst some of us don’t have that special friend in our lives, at least not yet, these animals have already found theirs! Pets that grow up with their owners on their own still get plenty of love, but those that grow up in pairs have always got a buddy right by their side to play, explore and nap with.
