Female rabbits can have one to seven litters of one to twelve young, called kits, in a year; however, they average three to four litters per year, and the average number of kits is five. In the South female eastern cottontails have more litters per year (up to seven) but fewer young per litter.
According to a University of Michigan resource on breeding mice for laboratory purposes, a female mouse can give birth to between four and eight litters each year. Each litter consists of an average of between six to eight mice. A female mouse reaches sexual maturity at between 6 and 8 weeks old. The gestation period for a litter typically lasts between 19 and 21 days. Mice are very common in laboratory research, especially in genetics, in part because of this quick generation time, but this quality also makes them a pervasive pest animal.
