Animal friends

More and more people like to have a pet now. The most popular pets are dogs and cats, but some people love to keep snakes and lizards as pets. Anyway, it means most people love animals and they realize animas are truly man's friends. It is not an easy work to keep a pet. If you do so, you need to spend a lot of money and time on your pets, right? You have to feed them, take care of them when they're sick, and of course, you have to play with them. On the other side, animals are helpful to people. For example, police dogs can help the police to catch the criminals much easier. And the old people will not feel lonely if they live with pets. All I know is we should be friendly to our anima friends and love them like we love our family members.
