WASHINGTON (WUSA9) -- Good news for four adorable African lion cubs at the National Zoo - they passed their swim reliability test Tuesday morning!
The four cubs, three males and one female, took a brisk paddle at the zoo and proved that they're ready to be on exhibit.
Born March 2, the 10-week-old cubs are one step closer to being ready to explore the yard with their mother, nine-year-old Shera.
Zoo officials say all four cubs were able to keep their heads above water, navigate to the shallow end of the moat and climb onto dry land. The shallow end of the moat is approximately two and a half feet deep, which could present an obstacle for young cats.
The side of the moat closest to the public viewing area is about nine feet deep and is an essential safety barrier that effectively keeps the cats inside their enclosure.
The cubs will make their public debut in mid-June once all vaccinations have been administered.
