A lot of people want to have a pet. But there are some animals which can’t be kept by human. First, there are endangered species of animals. There are people who get them through smuggling or getting extras (when the zoo gets more animals then they really need they often sell them away without proper progress and confirmations.) from zoo after paying them. Raising them personally is counted as serious illegal problem. Second, the wild animals which are big and furious can’t be handled unless they were living with people since they were babies. (Monkeys we see in zoo are domesticated. They were handled since they were babies. Monkeys are actually very wild.)
Not just reasons we can’t raise some animals, we need to think about if we can be responsible on its life-if we can feed them, and provide them a proper environment-before we buy them.
