Common Rat, Rattus Norvegicus
Large rodent which can measure up to 40 cm in length (including the tail). Fur colour can vary but is generally dull grey in colour.

Rats are omnivorous and whilst they generally feed on cereals and grains, if hungry they can take small chicks and eggs. One of the main characteristics of rats is that they are Neophobic- very wary of anything new and they can take 4-5 days before they except a new object. They prefer small-enclosed spaces and get around by smell and touch. They like to be up against something as they travel like a wall or pipe.

They carry a number of diseases, such as Weils Disease.

Rats take between 2-3 months to reach sexual maturity and can have up to 7 litters per year with the average litter being around 8.
