Rats Vs Mice

To many people and cultures rats and mice are seen as the same animal, mice are thought to be young rats. In some languages there is only one word for both animals – rat. However, this is not the case they are distinctly different animals, with their own life cycles, habitats, health issues etc. To help you decide what infestation that you may have, we have constructed a simple table to help tell the difference between rats and mice.
