However, rats eat much more at each site than mice. A house mouse's home range is rather limited, ranging approximately 10-30 feet. Mice are extremely curious and will explore their territory daily and any new object introduced into their home range. Prolific breeders, house mice will produce offspring year round under ideal conditions. Mice are also color blind and can recognize objects that are 10 feet or closer.
Mice have an average life span of one year.
They frequent many feeding sites during their activity period, sampling small amounts of food from each site. Young Norway and roof rats can be sexually mature and capable of mating at 3 months of age. Female Norway and roof rats can be pregnant with a new litter and still lactate to feed their young. However, the gestation period may be slightly longer. Female Norway and roof rats average 3 to 7 litters per year.
