The Sumatran tiger is the smallest of the tiger subspecies with less than 400 estimated to remain in the wild. However, the good news is this tiger family is growing at Australia Zoo in Queensland. Australia Zoo, owned by the Irwin family, welcomed the historic birth of a pair of Sumatran tiger cubs in 2013, and then again with another pair in 2016!
Kaitlyn, a purebred Sumatran tiger, gave birth to her pair of healthy newborn tigers—Hunter and Clarence—after approximately 6.5 hours of labor on Aug. 22, 2013. Hunter and Clarence made history by being the first Sumatran cubs born in the zoo, a significant achievement indeed, considering the Sumatran tiger is critically endangered.
