Many people like to keep pets. Some of them have only one pet but others keep a lot of animals at home. I like pets because they bring happiness. Number of pets usually depends on if a person lives in a big or in a small house. If a person lives in a small house, they can not keep a lot of pets. If people live in a big house they are able to keep more pets. In small house we can keep cats, small dogs, birds or fish. In a big house different kind of animals can live. It is important to remember that we must take care of our small and big pets.
