However, as a general rule, ligers do not prey on people, owing mostly to the fact that they are reared in captivity and are fed very well, given their nature as alien hybrid species. A liger, as shown in the above illustration, is more than capable of murdering a human being. However, since its survival depends on its keeper, it would never act against his or her interests. Ligers are usually kept as pets because of their unique appearance and also due to the fact that they are highly intelligent animals that can be trained to do many things. Also, because they combine traits from both lions and tigers, they are much harder to break-free than either of them alone. Unfortunately, not all liger owners treat their animals with the same level of care that they would if they were keeping a lion or tiger. Some keepers may even sell their ligers off in the black market or use them for entertainment purposes only, which is illegal. There have been reports of liger attacks before now, but most involve small children who are often lured away from their parents' sight. Only one recorded liger attack resulted in death. This incident occurred in South Africa in 1990 when a 38-year-old man named Donald MacKinnon was killed by his liger son, Taj. Before he died, Mr. Mackinnon's wife managed to run away with their daughter, leaving her husband's body behind.
