A Norway rat is red or brown in color with a white underbelly. It has coarse fur, small ears, and a tail that is scaled and no longer than the body and head combined.
Length ranges from 10 to 12 inches.
Food and Water Consumption
Although the Norway rat prefers grains, fruit, nuts, and meat, it will eat just about anything. Water intake varies based on what kind of food is available. When eating dry foods, the Norway rat consumes ½ to 1 ounce of water per day.
Norway rats are commonly found in fields, woodpiles, farms, and buildings. If they have invaded a building, they prefer living on the ground level or in the basement. Nests are made from shreds of fabric and paper.
