What color is the fur of Norway rats?

The fur of Norway rats is generally described as reddish-brown, which is often combined with a greyish underside. This distinctive coloration helps the Norway rat blend into its natural environment, providing some camouflage against predators. The reddish-brown coloration is a key identifying feature that differentiates them from other rat species, where fur color can vary significantly. This understanding of rat identification is crucial for pest control professionals, as it aids in recognizing the species when encountered in various settings. The other colors mentioned do not accurately represent the natural fur color of Norway rats, making it essential for study and recognition in pest management practices.
