In Canada you can find dogs, cats, horses etc. In almost every family. They are their pets. People love these pets and regard them as their good friends. Before they take them to their houses, they take them to animal hospitals to give them injections（注射） so that they won’t carry disease（疾病）. They have animal food shops. Some people spend （花费） about two hundred Canadian dollars a month on animal food. When you go to Canadian homes, they will be very glad to show you their pets, and they are very proud of them. You will also find almost every family has a bird feeder in their garden. All kinds of birds are welcomed to come and have a good meal. They are free to come and go and nobody can kill any animal in Canada. If you kill an animal, you will be punished （被处罚）.
People in Canada love animals very much. Do you know why? One of the reasons may be: In their families when children grow up, they leave their parents and start their own lives. Then the old people will feel lonely（孤独的）. But pets can solve（解决） this problem. They can be good friends and never leave them.
