The Female (The Queen)

Once the breeding season begins, in general around January or February, the female, called the queen, will go into heat multiple times until the end of the breeding season in October or November. The heat cycle is greatly affected by the ratio of daylight to darkness and by temperature. In cat colonies, for example, with 14 hours of light and 10 hours of darkness, as well as constant temperatures, female cats will be in the breeding cycle year-round.
