The teenagers as well as the adults are waiting for the first Sunday of August to celebrate "Friendship Day," a day that we dedicate to our beloved friends to show them how important they are in our lives. Exchange of Friendship Day gifts like flowers, cards and wrist bands are a popular tradition of the day.

Alike humans, the wild creatures also have emotions to make friends. Though such friendships can be seen very rarely in daily life, they do exist.

From a dog feeding a tiger cub to a cat sharing a meal with a mouse, the photos below show some unlikely friendships that exist between wildly different animals.
