　　Three tiger cubs, born to Siberian tiger parents, were abandoned by their mothers. The staff members of Nanning zoo in Guangxi Zhuang Autonomous Region found surrogate dog mothers to breast-feed them. After a period of time, the mother dog has not only adapted the role as being tiger cubs` nanny, but also shoulder the duties to protect the cubs. And the mother dog`s three puppies also get along well with the three tiger cubs.
