The estrous cycle of rats lasts for about 4 days, during which time the female rat goes through different stages, including proestrus, estrus, metestrus, and diestrus. During estrus, the rat is receptive to mating, and ovulation occurs. However, unlike in humans, ovulation is not necessary for sexual behavior during the estrous cycle in rats.
