| Animal friends Many people like to keep pets in the world, such as dogs and cats, but it is difficult to keep pets. It will take us a lot of time and we should spend lots of money on it. Animals are helpful to people. For example, a police dog can help the police catch bad people quickly and easily, and without dos’s help, the blind men can’t go anywhere alone. The pets can let us be happy as well. And the old people will not feel lonely when they stay with pets. Animals are friendly to people, so we should be friendly to them as well as to our family members. So why not keep pets as friends at home? I think you will love them at once.
