Domestic animals and preferences for pets

Animals are in the planet Earth since relative long time ago. Humans are animals too, but they domesticated other animals and also used some for different goals. The animals have diverse purposes for humans, such as affection, fun, therapy, remedies, alimentation, transport, studies, researches and other finalities. Depending on the species, some of those purposes may be more common than others. However, sometimes, due the culture, tradition, religion, politics of protection, or other rasons, some of those finalities are refused to be applied to determined species or all in general by some people. For example, it happens when someone loves animals and so becomes a vegetarian or a vegan, trying to avoid the death of more of them destined to the feed. That affection between humans and animals is still present around the world. Several animals can be our friends. Many of them are four-legged. For example, the dog is popularly known as man's best friend. So, some people care for pets and raise them.
