The Smithsonian’s National Zoo welcomed its newest animal Tuesday with the birth of a Sumatran tiger.

Great cat keepers watched the cub’s mother — an 8-year-old Sumatran tiger named Damai — give birth at 4:17 p.m. July 11 via a closed-circuit camera, according to the zoo’s website. The cub’s sex is still unknown as animal care staff are giving mother and baby time to bond.
