Ligers are the cross of a male lion and a female tiger, and they are the largest of all living cats and felines. Their massive size may be a result of imprinted genes which are not fully expressed in their parents, but are left unchecked when the two different species mate. Some female ligers can grow to 10 feet in length and weigh more than 700 pounds. Ligers are distinct from tigons, which come from a female lion and male tiger. Various other big cat hybrids have been created too, including leopons (a leopard and a lion mix), jaguleps (a jaguar and leopard mix), and even lijaguleps (a lion and jagulep mix).
