Their are 6 young in a litter, and 8 litters per year; adults live about 15 – 18 months.

The Norway rat usually nests in basements & lower portions of buildings. They often burrow in the soil and have extensive runs. The Norway rat is active primarily at night and they are decent climbers and excellent swimmers. Rats are suspicious of changes in the environment or new foods.
