It is not the first time a potentially dangerous north American wild animal has been brought to heel by a family pet.
In 2006, a ginger cat - also called Jack - chased a black bear up a tree in West Milford, New Jersey.
When the bear eventually climbed down, Jack the cat chased it up another tree.
The bear only escaped when Jack's owner called him into the house.
