In some North European countries such as Norway and Sweden, there is a kind of rats called traveling rats, which produce their young seven or eight times a years. The young will grow up in about six months and produce their own young. So, in a few years these rats increase in great numbers. Usually they live together in holes in the depth of high mountains and live on grass and roots of trees. What is strange is that every three of four years, they will migrate in thousands or even in millions, leaving a few of them in their original living place.The migration mainly goes on atnight. In daytime, they eat and rest. At night, they go just straight forward, even if there is a river before them:  the rats in the front will drown themselves while the ones after them will make their way on the bodies of the drowned rats. Sometimes the number of the moving rats may decrease because of illness, bad weather or attacks from eagles, wolves ang so on. Once they reach the seaside, they keep on fearlessly and get drowned to the last one of them.Why do they make such a migration? Some suggest that there may be too many of them to find food. Some suggest that the migration us the result of the bad temper of the rats.
