Brown Rat (S/F) / (S/F-T/G)

The brown rat (Rattus norvegicus) is a species of rodent in the family Muridae. It is also known as the Norway rat, Parisian rat, common rat, street rat, sewer rat, Hanover rat, or wharf rat; domestic breeds are sometimes called lab rats or fancy rats, but these common names can also be applied to other rat species bred in captivity. While native to eastern Asia, this rat is highly adaptable and can become invasive in almost any environment; as a result it is found in most of the world.
