Today almost every family has a pet. Speaking about the reasons, I believe that most people keep animals because they make their lives happier. Also parents usually buy a pet for their children. It can help them become more responsible. In my opinion, cats, dogs and parrots are the most popular pets in big cities. They are widespread because all of them can easily live within the apartment. But it is important for all owners to keep in mind that having an animal is a big responsibility. Life of creatures depends on them. They should always remember to feed, walk with a pet. And if necessary to play with it. In conclusion, I think that pets make our lives happier. But it also a big responsibility to keep one. Owners should be very attentive to needs of their pets.
