     In Canada you can find dogs, cats, horses, etc. in almost every family. These are their pets. People love these pets and have them as their good friends. Before they keep them in their houses, they take them to

animal hospitals to give them injections(注射) so that they won't carry diseases. There are many special

animal food stores, though people can get animal food in almost every kind of store. Some people spend

around two hundred Canadian dollars a month on animal food. When you visit people's houses, they will

be very glad to show you their pets and they are very proud of them. You will also find that almost every

family has a bird feeder in their garden. All kinds of birds are welcome to come and have a good meal. They are free to come and go and nobody is allowed to kill any animal in Canada. They have a law against
