How Long Does Cats Stay in Heat?

Normally, this means cats can go in heat for a period of six months between early spring and early autumn in the most part of the world.

Your feline’s yowling and odd habits might have you wondering for how long the heat cycle lasts and when it will end. Here’s the answer.

Felines remain in heat for 4 to 10 days, and this cycle can occur every couple of weeks.

A cat’s first heat cycle, called estrus, occurs at sexual maturity — which, depending on the type, might be when the kitty is anywhere from 5 months old (for Siamese cats, for instance) to 10 months old (particularly for a few of the longer-haired types, such as Persians).

As an outcome, many individuals spay their cats as soon as possible so their felines do not experience a heat cycle. Of course, spaying likewise helps prevent family pet overpopulation.

The Stages of Heat Cycles in Cats

Proestrus: During proestrus, the queen may draw in unneutered males (toms,) but she is not receptive to breeding yet.

Proestrus typically lasts a day or two. Queens in proestrus typically reveal no outside signs.

Estrus (heat): Next, the queen gets in estrus, or heat. For about a week (give or take), she will attract males and is responsive to mating. During this stage, the queen might vocalize loudly, roll around, rub on things, and raise her rear end. She might also have actually a decreased hunger. If the queen mates throughout estrus, it will induce ovulation. The act of mating stimulates hormonal agent production that triggers ovulation. Queens normally have to mate about 4 to six times throughout estrus to become pregnant. The queen might mate with numerous males while she is in heat and give birth to a litter of kitties that have various dads.

Interestrus: If the queen does not mate or conceive throughout estrus, she will go on to interestrus. This is the duration in between warms. Her estrogen level drops and she displays no particular indications.

After about two days to three weeks, she will once again enter into heat. The cycle of proestrus, estrus, and interestrus will continue throughout the mating season or until the queen conceives.

Anestrus: This is the queen’s reproductive dormant duration. Her reproductive hormonal agents are not active and there is an absence of estrus cycle activity; she is not in season.

In feral and outside felines, heat cycles happen seasonally from spring to fall. This is since the queen’s hormonal agent production is promoted by the light of longer days. When the days are shorter (particularly from October to January) the queen is not stimulated to enter into heat. Indoor cats are exposed to extended periods of synthetic light and for that reason might continue to go through heat cycles all year round.

How to Identify the Heat Cycle

You might expect bleeding. Although a percentage of bleeding and discharge may happen, it is not common. The modifications are more behavioral. Examples consist of:

  • More affectionate
  • Rubbing against individuals or items
  • Rolling on the floor
  • Requiring more attention
  • Raising the hind quarters when rubbed or scratched
  • Becoming singing, even yowling at times
  • Urinating more often or marking on items
  • Trying to escape to the outdoors

Urinary markings serve a function to other felines. The pheromones and hormonal agents released in the urine suggest the female feline’s reproductive status. The scent can be so strong at times that you might observe male cats spending time outdoors even if your feline is an indoor family pet.

How Long?

So, how long will a cat remain in heat? Usually, the estrous phase will last in between a week and 10 days. However, if your feline isn’t able to mate and become pregnant, she’ll likely enter into heat again at some point within the next 3 weeks. Some felines who aren’t enabled to reproduce might appear to be basically constantly in heat.

What Can You Do?

Have your feline made sterile to avoid reproduction. You can spay as early as 8 weeks of age, however talk to your vet. If a feline is currently in heat, some vets might wait until the cycle is over prior to performing the spay.


  • Felines do not have to have a litter of kittens before they are spayed.
  • Replicating does not make them more affectionate, change characters or fix any issues. It does add to pet overpopulation.
  • Cats can conceive throughout their first heat cycle, and they do not discriminate when it comes to discovering an offered male — they will mate with their parents or siblings.
  • Cats can return into heat right after delivering.

If you cannot pay for to purify, call your veterinarian or regional gentle society to see what choices are available. A few times each year, the regional shelter here has actually a day dedicated to making sterile cats, and it costs only $10.
