temperate Asia, the Brown Rat was introduced into Britain
by trading ships from Russia in about 1728. Brown Rats
are mainly nocturnal or crepuscular and spend the day
sleeping in nests filled with soft materials. Their nests
are built as near food as possible.

Rats damage many materials,
from wood to water pipes: this is because they gnaw anything
available to keep their incisors short. The cheek teeth are
rooted. The front feet are used for digging burrows.
The Brown Rat is larger and
more fecund than Black Rat, but is more shy of people so is
responsible for less disease transmission.
