Now a lot of families keep pets 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 favorite is the cat and the third favorite is the bird. These small animals are very cute and friendly. They are like people's family. People let them wear beautiful clothes and have nice names. They also give their pets nice food. They buy food for their pets in pet shops. They keep them tidy every day. Pets 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）. The pets are like their children and they love them very much.
So pets are very important. I think every family needs pets.
