There's nothing more wonderful than having a very best friend, except maybe getting the chance to grow up with him or her! And while some of us may still be searching for that one true friend, the animals in the photographs below have already found each other and are quite content to be sharing their lives together.

In the following photos you'll find some of the most adorable and even some of the most unlikely of friendships, like best buds Riff the pet rat and his doggie guardian Osiris. 

If you've been contemplating getting a buddy for your own pet, hopefully this list will have you convinced that doing that could be one of the best ideas ever! And if you've got pictures of your own pets growing up with their best buddy, please go ahead and add them to the list! We'd love to see them!
