A litter of white lions now have names, the Toronto Zoo announced on social media Thursday.

In a video posted to Facebook, the zoo revealed that the five-month-old cubs are named Gus, Hank, Oliver and Harrison.

Although the zoo often lets the public choose names for animals born in Toronto, this time, the cubs were named by the zookeepers that have worked with them since birth.

The cubs were born at the zoo to mother Makali and father Fintan on Sept. 27, 2015, and have grown to weigh more than 30 pounds. They will eventually grow to be weigh between 260 and 440 pounds.

The zoo says the fast-growing cats are "very active, playful and rambunctious."

The cubs can be seen by the public in a special exhibit open Saturdays and Sundays from 11 a.m. to 2 p.m., weather permitting.
