The Roof Rat is an excellent climber and gets their name because they usually live high off the ground, like on the roof of a building. They have a very poor vision and are colour blind, but they have extremely strong senses of hearing, smell, touch and taste. Rats have four to six litters a year and each litter has 6 to 12 babies in it. These rats are only pregnant for about 21 to 23 days and they can start reproducing when they are three months old.
Roof Rats prefer eating fruits, berries, vegetables, cereal, pet food, nuts, grain, slugs, snails and rotten food.
Roof Rats are excellent climbers and they usually live in spaces on the tops of buildings, on roofs or in attics. They also live in sheds, garages, boxes, ceilings, under floors, in wood heaps and in thick grass.
Roof rats cause damage to structures by chewing, eating stored foods and carrying diseases, such as Hantavirus. They are most famous for spreading the highly contagious bubonic plague in the Middle Ages. Rats will also attack both animals and humans. Human babies and even adults have been killed in rat attacks.
