At the present time, many people have pets and there are more kinds of pet available in the market than in the past. However, someone may claim that raising pets is waste of money and time. The money spent for them should be donated to the poor who can not find even their meals. From my perspective, there are both advantages and disadvantages in keeping animals. For some people, pets can bring great benefits to them. In my case, if it is not necessary, I prefer not to keep pets in my house.
