  Norway rats are the ultimate pests. They host loads of diseases, including the plague, and can infest those bitten with a sickness known as “Rat Bite Fever.” Norway rats also destroy billions of dollars worth of crops and food stores each year! As if that weren’t enough, they also cause fires by chewing electrical wires in buildings… Nice rat…  
  An average female Norway Rat can produce up to 70 young per year!
