Visitors will be able to watch for the cubs on an external monitor that shows what is happening in their cage, the zoo said in a statement Thursday. But the lions often spend a great deal of time in indoor areas where they cannot be seen.
The zoo did not say which of its two 5-year-old lionesses named Okoa and Cora delivered the litter.
The last lion birth at the zoo took place two years ago with the arrival of siblings Cabara and Catali. They were transferred last April to the St. Louis Zoo in the United States.
