Keeping wild animals as pets

I think that keeping wild animals as pets is very stupid and dangerouse idea. Wild animal cannot behave itself like a cat or a hamster. It thinks about the family it lives with as about other animals and it tries to compete. It tries to make everyone obey it, it wants to be a leader. Wild animal is much stronger than a man, it can harm to anyone. That's why I think that wild animal mustn't live together with people.
