Rat vs. Mouse: Understanding the Key Distinctions

Grasping the distinctions between mice and rats is important for researchers, pest management professionals, and homeowners aiming to safeguard their homes from these invasive rodents. While both are members of the rodent family, they exhibit unique traits that distinguish one from the other. Typically, rats are heftier with bulkier torsos, extended tails, and sizeable heads featuring comparatively small ears and eyes. In contrast, mice are more diminutive, with finer characteristics, including ears and eyes that appear larger than their body size.
