What do you get if you cross a lion and a tiger? Answer: A liger.
The liger is a cross between a male lion and a female tigress. It is the biggest known cat in the world. They are the result of cross-breeding. Cross-breeding is very common with dogs and cats and this is why there is such a large variety of dog and cat breeds in the world. Ligers are extremely rare and are thought to only be born in captivity. This is because the two species come from different
continents – lions from Africa and tigers from Asia.
The largest known Liger is called Hercules and is over 6 feet tall. He is in the Guinness Book of Records for being so big! (by Prof. Simon Smith)
