Do Cats Have Periods? Cat Estrous Cycle & Menstruation

About Cats Cat Estrous133

As a cat owner, you may have wondered whether cats have periods like humans do. The answer is no, but cats do have a reproductive cycle that is different from humans. In this blog post, we will explore the reproductive cycle of cats and how it differs from the menstrual cycle in humans.


The Estrous Cycle in Cats

Cats have an estrous cycle, which is also known as a heat cycle. During this cycle, female cats become receptive to mating and can become pregnant if they mate with a male cat. The estrous cycle can last anywhere from a few days to a few weeks, and it typically occurs every two to three weeks during the breeding season.

During the estrous cycle, female cats may exhibit certain behaviors, such as increased vocalization, restlessness, and rubbing against objects. They may also show physical signs of being in heat, such as a swollen vulva and increased grooming of the genital area.

How the Estrous Cycle Differs from the Menstrual Cycle

Unlike humans, cats do not shed the lining of their uterus if they do not become pregnant. In humans, the menstrual cycle is a monthly process in which the lining of the uterus is shed if a fertilized egg does not implant in the uterus. This shedding of the lining is what causes the bleeding that is commonly referred to as a period.

In cats, the lining of the uterus is reabsorbed by the body if the cat does not become pregnant. This means that cats do not experience bleeding or a menstrual cycle in the same way that humans do.


In conclusion, cats do not have periods like humans do. Instead, they have an estrous cycle that is characterized by increased receptivity to mating and physical and behavioral changes. Understanding the differences between the reproductive cycles of cats and humans can help you better care for your feline friend and ensure their reproductive health.
