Two lion cubs born at the National Zoo in January will go on exhibit this May.

A message to Friends of the National Zoo members says the exhibit will be open to the public on May 9 from noon to 1 p.m. They will also be on exhibit from 11 a.m. to 1 p.m. on May 11 and 12. “Weather and cub behavior dictate whether or not the lion cubs will be outside during viewing times,” according to the Zoo.

Here’s an update on the cubs, including the four born in May:

The lion cubs are all doing quite well! Naba’s girls weigh about 30 pounds now, and Shera’s cubs range from 19 to 20.5 pounds. Shera’s cub that had the limp is showing great improvement. His limp is very slight, and his blood-work came back normal this week. In fact, he seems to be outcompeting his siblings when it comes to eating because he is now the largest cub from his litter!

And here’s what you’re in for this May.
