Now a lot of families keep pets（宠物） in their houses. Most pets are small animals, such as cats, dogs, fish, snakes, birds and so on.
Dogs are the favorite pets. The second favorites are cats and the third favorites are birds. These small animals are very cute and friendly. People usually have them as their family members. They look after them very well, they let them wear beautiful clothes and their pets have nice names. They also give their pets nice food . They buy food for their pets in pet shops. They keep them clean every day.
Pets are all very happy. Many pets have their houses and beds. They often go out to relax and take a walk with people in the park in the morning.
Some children like pets because they need a friend to play with at home. Many old people don’t live with their children, and they keep pets at home just because they often feel lonely（孤独的）. They have them as their children and they love them very much. So pets are very important. I think every family needs pets.
