KUSA - The Rocky Mountain Arsenal got 20 new residents Thursday night – and prairie dogs probably won’t be very happy.
Black-footed ferrets were once thought to be extinct. They are still considered one of the most endangered mammals in North America.
The 20 ferrets were brought into the Rocky Mountain Arsenal to help control the prairie dog population.
They will be tracked and monitored this month to make sure they are adjusting to their new home.
