Hercules is a liger - which means his mother is a tiger and his father is a lion. Ligers are the largest cats in the world - they are bigger than both tigers and lions.

Hercules is the biggest liger in the world. He is 12ft tall, weighs 900lbs and eats 25lbs of meat and drinks a gallon of water every day

"As a mixture of the world's largest two big cats, Hercules is an impressive specimen and a pretty well balanced and relaxed guy too," said Dr Bhagavan Antle, the founder of The Institute of Greatly Endangered and Rare Species (TIGERS) in South Carolina. "His parents Arthur, a lion, and Ayla, a tigress, were outstanding cats and this is obvious when you take a look at Hercules. The social side of his personality of course is inherited from his father and the pensive, observant nature is inherited from his mother."

Hercules was taken to a set built to look like London. You can see Hercules in action in the video below...
