RATS

Do you believe a couple of rat, just a couple can produce 15,000 descendants a year? Rats are very easy to breed. In fact, many people end up with unplanned baby rats! Rats can reach sexual maturity at 2 month of age, so the sexes should be separated at this age. Rats don’t recognize incest, so brothers and sisters and even mothers and sons must be separated. Rats don’t have a breeding season, although very hot or cold temperatures will reduce breeding. Females of breeding age come into heat all year round, every 4 to 5 days, unless they are pregnant or nursing As a female approaches menopause at about age 18 months of age. You can’t count on a female being completely infertile until she is 2 years old.
