Brown Rat
Rattus norvegicus
Adult brown rats are adaptable omnivorous rodents found in burrows, sewers, farms, riverbanks, warehouses, and cities across much of the world. They forage mostly at night, gnaw through tough materials, swim well, and retreat along memorized paths to underground dens or hidden nests. Their diet includes grains, seeds, fruit, insects, small animals, eggs, carrion, and human refuse. A notable fact is that their incisors never stop growing, so constant gnawing keeps the teeth worn to a usable length.
