Dear editor,
Recently we have had a discussion on whether people should keep pets at home in cities. Some students
don't agree to keep cats or dogs as pets. They think they can make our environment dirty. They will make so
much noise that some people cannot have a good rest at night. What's more, they will hurt others at times.
On the other hand, some students think keeping pets can comfort the old. They will not feel lonely any
more if they keep pets as their friends. Besides, they think if we can get on well with them, our life will
become more colorful.
In my opinion, it's good to keep cats or dogs as pets. But we should take good care of them and clean
out the ground in time. We should try our best to stop them from making trouble others.
