Do Cats Have Periods?

As an avid researcher, I am here to answer the question “Do cats have periods?” This is one of the common inquiries of cat owners and animal lovers. In this short write-up, I will discuss feline estrous cycle or heat cycle and how it differs from menstrual cycles of humans or other animals.

Understanding Feline Reproductive Cycles

Cats are fascinating creatures, and as their owners, it’s important to have a good understanding of their reproductive cycles. One question that often arises is whether or not cats have periods, like humans do. The short answer is no, cats do not have periods. However, this doesn’t mean that they don’t go through reproductive cycles or experience hormonal changes.

The Estrous Cycle

The feline reproductive cycle is known as the estrous cycle, which is different from the menstrual cycle that humans experience. The estrous cycle is divided into four stages: proestrus, estrus, metestrus, and anestrus. During the proestrus stage, the female cat will attract males but is not yet ready to mate. This is followed by the estrus stage, during which the female is receptive to males and will mate. The metestrus stage is when the female’s body is preparing for pregnancy, and the anestrus stage is a period of inactivity in the reproductive cycle.

Common Misconceptions

One key takeaway from this text is that while cats do not have periods like humans, they do go through reproductive cycles known as the estrous cycle. It’s important for cat owners to be aware of the stages of this cycle and the behavioral and physical signs that indicate when their female cat is in estrus. Understanding feline reproductive cycles can also help dispel common misconceptions, such as the belief that cats bleed during their cycles or go through menopause like humans.


One of the most common misconceptions about cats and periods is that they bleed like humans do. However, this is not the case. Female cats do not experience bleeding during their estrous cycle. Instead, they may have a slight discharge, which is usually not noticeable.

Another common misconception is that cats go through menopause like humans do. However, this is also not true. Female cats can continue to reproduce throughout their lives, although their fertility may decrease with age.

Signs of the Estrous Cycle


During the estrus stage of the estrous cycle, female cats may become more vocal and may meow loudly or yowl. This is a way for them to attract male cats.

Increased Affection

Female cats may also become more affectionate during the estrus stage. They may rub against their owners or other cats more frequently and may even become clingy.

Changes in Behavior

Female cats may also exhibit changes in behavior during the estrus stage. They may become more restless and may pace or circle more frequently. They may also become more aggressive toward other cats or animals.

Physical Signs

In addition to behavioral signs, there are also physical signs that can indicate that a female cat is in estrus. These can include:

  • Swollen vulva
  • Increased urination
  • Licking of the genital area
  • Rolling on the ground
  • Tail held to the side

How often do female cats go into heat?

Female cats can go into heat as often as every two to three weeks during breeding season, which typically occurs from early spring to late fall. However, not all cats will go into heat during this time, and indoor cats may experience estrous cycles year-round.

What are the signs that a cat is in heat?

Some common signs that a cat is in heat include vocalization, restlessness, and increased interest in mating. Female cats may also rub against objects and display more affectionate behavior. They may also have a swollen, reddened vulva and discharge from their genital area.

What should I do if my cat is in heat?

If your cat is in heat and you do not plan on breeding her, it is recommended to have her spayed. This helps prevent unwanted litters and can also reduce the risk of certain health problems, such as reproductive cancers. In the meantime, you can try to keep your cat comfortable by providing plenty of attention and playtime, as well as keeping her indoors to prevent mating.
