The gestation period for cats is about two months, with an average length of 66 days. The size of a "litter" is usually three to five kittens. Kittens are "weaned" at between six and seven weeks, and cats normally reach sexual maturity at 5–10 months (females) and to 5–7 months (males). Females can have two to three litters per year, so might have up to 150 kittens in their breeding life of about ten years.
