From the San Diego Zoo Safari Park:
The San Diego Zoo Safari Park's two Sumatran tiger cubs took a catnap after a morning spent exploring their exhibit. Conrad claimed the top spot, while brother Thomas chose to be near, rather than on their mother, Delta.
The 3-month-old male cubs made their public debut on Tuesday and will be on exhibit on Wednesdays, Saturdays and Sundays, from 9 a.m. to noon. The Safari Park is fund-raising to build a new, forested tiger haven that will offer up-close views of these fascinating felines and highlight conservation efforts for the species.
There are fewer than 350 Sumatran tigers in the wild. Scientists estimate that this species could be extinct in its native Sumatra by 2020 unless drastic measures are taken to protect and preserve it.
