Which rodent is known for its heavy body compared to a roof rat?

The Norway rat is known for its heavy and robust body compared to the roof rat. This species typically exhibits a stocky build, with a broad head and thicker body, which distinguishes it from the more slender and agile roof rat. Norway rats are generally larger in size, often weighing more and measuring longer than roof rats, which have a more elongated body and are better adapted to climbing. This distinction in body type is particularly important in pest control, as it helps professionals identify the species and implement appropriate management strategies. Understanding these physical differences not only aids in identification but also in understanding their behaviors and habitats.
