In some zoos, there is not enough space for animals to live. Animal cages are smaller than they should be. It is clear, to some extent, that some zoos do not have adequate space or living conditions for certain animals, but perhaps that is the best thing that can be done for them at that time. It could also be a temporary holding point until they are moved. No one really knows what is happening at the zoo or in the zoo; unless you work there. Zoos take animals out of their environment. The constant human presence only serves as a stress factor for most animals. This disrupts what is known as their normal behavior. Those in containment usually live in a large cage but do everything themselves and this keeps poachers and hunters away.
