Officials with the two zoos said Monday that the Amur, or Siberian, tiger cub named Zoya was accepted by the mother, a Sumatran tiger named Lola.
Zoya is the lone survivor of five cubs born July 9 to a first-time mother in the Philadelphia Zoo, and the mother rejected her.
Lola had given birth a day earlier to three cubs of her own, leading to the transfer of Zoya to Oklahoma City because of the similarities of the two subspecies of tigers.
Both Amur and Sumatran tigers are endangered with fewer than 500 of each believed to be living in the wild.
