Do hamsters keep mice away?

There are lots of questions we’ve been hearing whether can hamsters repel mice or rats. The answer can be both yes and no. Hamster can keep mice away mainly because they are different types of rodents. They elicit different scents that act like magnets. So the opposite attracts does not apply. Some hamster owners even experimented if hamsters would repel rats. The result is rat and hamster stayed away from each other. They also have different behaviors which make it a bit difficult to put them both in a single cage.

On the other hand, hamsters somehow attract mice. The reason does not have anything to do with the hamster’s scent but mainly because of food. If you have a hamster and it did not eat all of its food, rats would likely enter its cage and rob it of its food.
