Identification
for Norway Rat
A Norway rat is heavier and more thickset than the slender roof rat, with coarse brownish fur, a paler gray belly, and a blunt muzzle. Adults weigh roughly 7 to 18 ounces (≈200–510 g). The small ears do not reach the eyes when folded forward, and the scaly tail is shorter than the head and body — laid back over the animal it reaches only about the middle of the skull.
