Do Cats Have Periods? The Surprising Truth



f you currently have a female kitten and are asking yourself, “do cats have periods”, you’re definitely in the right place. A lot of people don’t know what to expect, or the answer to this question in general, so we’ve taken the time to answer it.


We will be answering the big question and other ones relating to female cats and if they have a regular period cycle to ensure that all pet owners can be as well informed as possible.

Do Cats Have Periods?

The answer to this question is both yes and no. Cats go through what is known as a regular heat cycle, also known as Estrus, which begins typically when they are 6 months old. While bleeding is not typically part of this situation, there are some cases of minor spotting.

Cats typically reach maturity by the time they are a little over 6 months old, but the timeline can differ for various reasons. Although, sometimes there is no reason at all, other than reaching their full growth.

A cat that is not spayed by a veterinarian before their heat cycle begins will go through it until the surgical procedure occurs.

How Long Do the Heat Cycles Last?

Cats are what’s known as seasonally polyestrous, which generally means that they will have more than one heat cycle during the season of natural breeding. There are quite a few things that will help to influence when the cycle begins, how long it lasts, etc.

For example, the number of hours of daylight in a single day and the temperature both affect a cat’s heat cycle. Overall, however, environmental and geographical factors are the biggest factors as to how long it will last and when it begins.

For example, female cats living in the Northern Hemisphere will typically begin a cycle during January until late fall. Cats who are located in tropical regions, however, could cycle all year round, but that only generally applies to strictly outdoor cats.

Signs to Look For

There are, interestingly enough, a couple of signs to look for that will let you know when your cat is in heat. For example, their vulva may begin to swell, but this is not always the most common sign.

A female cat who is about to hit their heat cycle, or one who is already in it, will walk around in sort of a frog pose with their behind positioned in the air. They will make a lot more noise than usual, act very unusually, and proceed to roll around frequently.

Vaginal Bleeding During the Heat Cycle

While some spotting can be seen, blood is generally not right during a cat’s heat cycle. Vaginal discharge with blood is generally associated with multiple different health issues, such as a pregnancy miscarriage.

Ergo, if you are seeing blood during your cat’s heat cycle that is more than a couple of drops, bring your cat to the vet immediately. This is especially crucial if your cat is already pregnant with a litter of kittens.

Why Do Cats Go Into Heat?

Cats go into heat because they have reached maturity and are ready to start breeding. They act so strangely during this period because they are basically showing that they are ready for a mate to impregnate them with a litter of kittens.

The heat cycle is natural and nothing to worry about. Although, if you have had your cat spayed at the vet you will no longer need to think about when your cat’s next heat cycle is.

Having a Female Cat Spayed


The only way to avoid the heat cycle, and your cat having kittens, is to have her spayed at the veterinarians. This surgical procedure eliminates the heat cycle and the discomfort and frustration that go along with it.

It also ensures that your cat cannot get pregnant, which is ideal for those who have outdoor cats but don’t want to deal with a surprise pregnancy.

Once a cat has gotten spayed, the hormonal influence and behaviors of the heat cycle are 100% gone, which is a blessing for some. A lot of female cats will howl all day and night during the heat cycle, for example.

Do Cats Have Periods?

When it comes to the big question, “do cats have periods”, you now know that it’s both a yes and no question. Cats have very sensitive systems, especially when it comes to the heat cycle, which is why it’s important to stay well informed and be ready when it happens for the first time.
