Norway Rat

Norway Rat

While almost with the same characteristics as mice, rats are typically distinguished from mice by their size. Rats are generally large rodents. A rat may grow to be 16 inches from tip of tail to nose, with a tail shorter than its body, light brown to dark gray in color, with a blunt nose, small eyes and small ears. The lifespan may depend on the species but on average live up to about a year.
