Rat vs Mouse
All of you have seen mice and rats at some point in time during your life. Since both of them fall under the category of rodents, most of you believe that they are similar to each other.
However, there are several points of differences between the two types of rodents. Although all of you may say that mice and rats differ from each other in terms of their size, it will be tough to distinguish between a rat and a big sized mouse.
Talking about size, mice vary in size ranging from 12cm to 20cm. On the other hand, rats have a size of around 40cm. Even the size of their heads is different to some extent. The primary difference between the two types of rodents lies in their heads.
The head of a mouse is way smaller than the size of a rat’s head in relation to their overall body. The head of a rat is much heavier and also shaped slightly differently from that of a mouse’s head.
The heads of mice are rather tiny, triangular with a pointy nose. Rats, on the other hand, have chunky, heavy, and blunt heads. However, mice are fortunate to have bigger sized ears as compared to rats. The ears of a mouse are much bigger in comparison to the overall size of their body.

What is a Rat?
When you talk about rats, these are those large-sized rodents that appear somewhat similar to a mouse. However, unlike a mouse, a rat would seldom appear inside homes.
These are normally found in locked or abandoned factories and around shops and storehouses. Rats are medium-sized rodents that may grow to almost 40cm or even bigger.
One of the primary areas of difference between a mouse and a rat is the size. Rats are bigger than a mouse and also weight much more than the latter category of rodents.
Amongst the several species of rats, the two of the most popular species are the black rat or Rattus rattus, and Rattus norvegicus or the brown rat.
You need to remember that the term rats is used to point out other types of mammals that are not exactly rats.
These include kangaroo rats that are a large number of species and North American pack rats that are primarily wood rats.
What is a Mouse?
A mouse is another type of rodent that is normally characterized by its small physical structure and pointed snout. These small-sized rodents are rather timid by nature and have small rounded ears.
One of the most popular amongst various species of mice is the house mouse, which is also known as Mus musculus. Some people also have this species of a mouse as their pets and scientists use it for various experimentation purposes.
If you believe that mice and rats are the same, then you are highly mistaken. A mouse is way smaller in size than a rat.
They are also commonly found in houses, especially the kitchen area. On the other hand, rats are mostly found in empty storehouses and factories. Some animals and birds, such as wild dogs, snakes, eagles, and cats prey on mice.
The natural ability of mice to adapt to any environment makes it one of the most popular and successful mammalian that lives on this planet.
Mice are also termed as vermin due to their large-scale ability to spread diseases and causing structural damages to crops and various other things through their feces and parasites.
