Many people like pets because they are cute and useful. I like it, too.

But it is not easy to take good care of the pets. You should spend lots of time and money taking care of them. If you don't, they will die .

Animals are useful to people. For example, police dogs can help policeman catch bad guys. And resuce dogs can resuce people, too. Pets can also make us happy and make old men not lonely.

We shouldn't kill or hurt animals very often. We should keep friendly animals as our family members.
