Description : Brown rats have a stocky, robust body with brown or greyish-brown fur. They have relatively small ears and a blunt nose. Adults typically measure 20-28 cm (8-11 inches) in length, not including the tail, which adds another 15-22 cm (6-9 inches). They weigh between 140-500 grams (5-18 ounces).

Brown rats are found throughout much of the world, in both urban and rural areas. They are often found near human settlements, but they can also be found in forests, fields, and other natural habitats.

Brown rats are social animals that live in groups. They are primarily active at night and spend much of their time foraging for food. They are good climbers and can often be found in high places like trees, attics, and rooftops.

Brown rats are omnivores that will eat just about anything, including grains, fruits, vegetables, insects, and small animals.

Female brown rats can have up to 6 litters per year, with each litter consisting of 6-12 young. The young are born blind and hairless, and they are cared for by their mother until they are weaned at around 3-4 weeks of age.

Brown rats are highly adaptable and can thrive in a variety of environments. They have strong teeth and jaws that allow them to gnaw through wood, plastic, and other materials, and they are capable of squeezing through very small spaces.
