A house mouse has the following:

  • Long tail that starts thick and gets smaller.
  • Big feet
  • Large body (Adult is approximately 25cm with out the tail)
  • Droppings are considerably larger than a mouse and 1 to 2 cm in length. Rats tend to use one area as a toilet.

Common Mistakes

Sometimes their may be confusion between the difference between rats and mice. This occurs when a baby rat is seen or caught. The best way to tell the difference in this situation is to look at the feet. A baby rats feet are completely out of proportion to the rest of its body. So much so it looks very strange and is unmissable in my opinion.
