First-time mother, Erin, gave birth to seven cheetah cubs earlier this month at the National zoo. Zoo officials say the cubs appear to be healthy and doing well. Keepers will perform a health check on the cubs when Erin is comfortable leaving them for an extended period of time. In the meantime, the keepers will continue to monitor the mother and cubs closely through den cameras and visual checks to ensure they are growing and developing normally. | Voice of America
