The door to the Department of Unexpected Interspecies Friendship is always open. A glance inside today reveals a trio of abandoned tiger cubs who’ve been adopted by an awesome pair of female pugs. The cubs were born at the Oktyabrsky Health Resort in Sochi, on western Russia’s Black Sea coast. After their mother rejected them the zoo keepers found two willing wet nurses in the form of these plucky little pugs. Because dogs and cats produce milk of differing composition, zoo keepers have to provide supplemental feedings to ensure the cubs receive adequate nutrition.

At the rate they’re growing, the tiger cubs will soon be larger than their adoptive canine mums. But for the time being the pugs seem quite pleased with their new roles.
