Norway Rats
The Norway Rat, also known as a brown rat prefers to live almost anywhere humans are. Rats are foragers that can survive on a huge range of foods, which has helped them spread so successfully across the world. Humans often dislike rats, but rats present a variety of benefits to their ecosystems as predator and prey, are popular pets and have contributed to advances in the fields of genetics, cognitive research, physiology, epidemiology and pathology.
