Introduction

Mice have a unique way of marking their territory, and their pee plays a key role in this behavior. You might be wondering why such a small creature can cause such a big fuss!

When you see mouse droppings or notice a faint odor, it's likely they've left their "calling card" behind.
In their tiny world, urine serves as a super important message system. Each mouse has a distinct scent that helps others recognize if they're friendly or not-so-friendly.

Plus, male mice often have stronger scents due to the hormones they produce, making their urine even more pungent.
