People train animals working in the circus. But there are animals that
are impossible to train. There are a couple of reasons. Perhaps they
wild or just not trainable or too large. But what kind of animals we
can't see in the circus? A giraffe and a Zebra, certainly not trained. Because they are wild and live in Africa or Australia... the Cat, the bull, the cow is also impossible to train. Cat - a pet who
loves to eat and sleep; the bull is distinguished by its size, and can
at once crush trainer. Leopard also is not trained. Of course, there are many such animals, but I wrote some of them. I think many animals you can
train, just you need to find a way.
