We have discussed the differences in terms of appearance. Now, I am just going to discuss the differences in terms of behavior. Stay with me!

Rat vs mouse – In Terms of Behavior

As we know, rat and mouse both belong to the category of rodents but there are differences in their behaviors.


If we talk about the boldness, the mice are bolder than the rats. Basically, the mice are more curious and try to find new things in their environment. On the other side, the rats are fearful and never try new things in their life cycle. It is difficult to catch the rats because they never come in front of you due to the fear inside them.

When we talk about the nesting of both then it is very clear that mice are more skillful to find the nest to live as compared to the rats. There is a benefit for the mice due to their size, they can live in the small holes and it is very easy for them to dig these holes. Mice are good climbers as well as the runners.

On the other side, the rates are a good climber but they have a big size and live in the big holes. So, it is easy for a human to target rats as compared to the mice. So, they try to live in the basement of houses or empty areas of houses.

Which is more dangerous? Rat vs mouse. So, to identify that which is more dangerous, we have to discuss some other factors. Let me discuss these factors.
