Not All Animals Make Good Pets
Some people think domesticating an animal is a noble act, but not all animals make good pets. Big cats like lions, cheetahs, and tigers may be cute as cubs, but they are tractable at best (they can be trained, but not tamed). Animals like reptiles often over stay their welcome and then end up being re-released, only to die in the wild. All animals are best off learning from their own. For animals that are unable to survive in the wild, they are better off at a facilty with trained animal experts, than someone wanting to show off their exotic pets.
