User:Jerry1015/Several facts of breeding liger or tigon

=== Liger, a big mammal who has the feature of both tiger and lion, is the offspring of a male lion and a female tiger. They are often breeding by zoo, and only small part of them are breeding naturally. Since lion and tiger do not live in the same area, it is not wildly happened. However, there are several problems of breeding liger or tigon. Many animal rights activists or organization claims it is a moral problem to breeding liger or tigon in purpose, such as entertainment of zoo or circus. Liger or tigon will suffer from a series of problems from their birth, to their death. When those unscrupulous business tries to get benefits on breeding liger or tigon, there is still another group of people try to stop this phenomenon. ===

Healthy problem
Those ligers or tigons will always have healthy problem. Liger are usually predisposed to gigantism. They will grow too big, which will lead many problems. First, their mother will need to cesarean in order to give birth. However not every mother lion or tiger can make it through. Then, their large size of body will make it too big for their organ. Organ failure issues are also common in liger’s illness. Not only organ failure but also many other illnesses that usually happened in big-cats hybrids such as neurological deficits (problems with brain function or spinal cord, which will lead vision and hearing flaw), sterility, cancer, arthritis, and short lifetime.

Tigons, on the other hand, are more likely to get physical and neurological disease. Moreover, it is nearly impossible for them to survive infancy. No matter liger, tigon or other unnatural big-cats hybrids, they all have higher risks to sustain injuries or get different kinds of disease that be mentioned before.

Debate
The exists of liger is always a big debate in the world. Many animal rights activists believe it is a moral problem to breeding liger. However, some others claim it is totally right to have liger. If tiger and lion live in the same area, it is possible for them to have offspring. According to National Geographic Television and Planet Carnivore on National Geographic, lions are evolving from leopards. On the other hand, the place that tigers resolved, there is also leopards live. So, it is not impossible for them to have same ancestors. In this condition, it is reasonable to have liger in this world.

Healthy problem is also not always happened in the liger. Some ligers are sterile and can breed and survive like normal kind of lions and tigers. A liger named as Sashata lived more than 24 years. So, it is another counter point of having liger. However, no matter it is right to have liger or not, it is always unmoral to reproduce them for entertainment and abandon them when they lose their value.
