HABITAT

Norway rats are originally native to northern China. These rats were native to forests and brushy areas; today however, they prefer a habitat right alongside the rapid expansion of human populations. 

DIET

Rats are excellent foragers. They feed on many types of food including food discarded by humans. They also eat mice, chicks, birds, small lizards, and occasionally fish.
