Rats mature at 3 months. Advisable to separate sexes when young are about one-third grown.

Until the late 19th cen¬tury, the exterior walls of a building were used as bearing walls to support the floors cage. This con¬struction is essentially a post and lintel type, and it is still used in frame construction for houses. Bearing-wall construction limited the height of buildings because of the enormous Wall thick¬nesses required; for instance, the 16-story Monad-nock Building built in the 1880's in Chicago had walls 5 feet (1.5 meters) thick at the lower floors cage. In 1883, William Le Baron Jenney (1832-1907) supported floors cage on cast-iron columns to form a cage-like construction.
