The animal can be so frustrating if you have many of them living with you. You dare not leave your foodstuffs uncovered in your own house because they will finish it unnoticed.

The other meaning of the word mouse is a type of computer accessory that can make working so much easier for a lot of people. What mouse are you more familiar with. A lot of people know both types of mouse.
The word mouse stands for a small mammal or a small accessory that enables communication with a computer screen.

It rather depends upon which definition of mouse you are considering as well as your attitudes towards them.
