Clever horse unlocks stable doors

A clever horse in America has been showing off her skills at opening stable doors for herself and her chums.

The 9-year-old animal named Mariska learned to open door latches at Misty Meadow farms in the state of Michigan.

Farm owner Sandy says Mariska played with things in her mouth when she was young and it progressed from that.

When the horses are out of their stables, they head to the grain room for food or out into the yard to where the grass is.

Check out the clip of Mariska in action!
