A Sumatran tiger at the Oklahoma City Zoo is pregnant. Ten-year-old Lola is due to give birth this summer. Sumatran tigers are a critically endangered species.

The Association of Zoos and Aquariums (AZA) Species Survival Plan® (SSP) for Sumatran tigers recommended that the OKC Zoo arrange for Lola to breed with her mate, 14-year-old Kami, according to OKC Zoo officials.

The OKC Zoo participates in AZA’s SSP and is committed to protecting Sumatran tigers and helping sustain their population, zoo officials said.
