A mouse is a small rodent with roundish ears and a long thin tail. Mice are smaller than rats, although they are similar and possibly related. Cats often consider mice prey. They are known for chasing mice, and many times killing them and even going as far as eating them. Bats are often considered "Winged-Mice," however this is not true, as bats are not a type of mouse nor are they even a type of rodent. Mice are also known for eating cheese.
