Animal friends 

Now many people like keeping animals as pets, such as dogs and cats. If you are going to keep pets, then you should buy pet food to feed them every day to keep them alive. You should buy shampoo for them to take shower to make them tidy. You should buy medicine and take them to the pet hospital when they have illness and pain. All of this you need money. Keeping pets really spends lots of their time and money. So keeping a pet is not easy.

Animals are helpful to us, and they help us a lot. For example, police dogs help police to catch the bad guys; pets can make their owners feel happy, and let the old men feel warm instead of lonely; the specially trained guide dogs can help their blind masters to find their ways and so on. And some animals have special function, for example, cats can catch mice. It will keep the mice away from the food and keep the food whole. Animals do many great things to us, right? They are useful, aren't they?

Perhaps you don't have an animal friend, you still need to be nice to them. However, animals help us when we are in need, we need to treat them as our family member. Animals are our friends, so we should be nice to them instead of shouting to them, right?
