What Is The Average Length Of A Heat Cycle?

You may have noticed that your cat is acting differently. She’s affectionate and purring more than usual, and she may be spending more time grooming herself. 

This might seem like an odd response to you, but it’s actually very normal cats go into heat every few months as part of their reproductive cycle.

Here are some things you should know about a cat’s heat cycle:

  • It lasts between four to seven days on average
  • A cat will go into heat two to three times per year
  • The first heat cycle begins at around six months old

When it comes to breeding ragdoll cats, it’s essential to understand how many times they can breed. Our comprehensive guide on how many times you can breed a ragdoll cat provides valuable insights into the breeding limits and considerations for responsible breeding practices.

How Long Do The Cycles Last?

You can expect your cat to have a heat cycle that lasts 5-7 days. The first time she goes into heat will be longer than subsequent cycles but hopefully not as long as when she is pregnant or nursing kittens.

If your cat is not spayed, she will go into heat every 3 weeks until she’s around 2 years old and then it will stop altogether.

Cycle TypeAverage Duration
Heat Cycle7-10 days
Sleep Cycle90-120 minutes
Menstrual Cycle28 days
REM Cycle (in humans)90-120 minutes

When Can You Tell Your Cat Is In Heat?

The length of the heat cycle varies from cat to cat, with some cats going into heat for up to 14 days and others for just six days. 

The reason for this is that some cats have shorter cycles than others. If you have a female cat that has been in heat before, then it’s likely she will go into heat again after just 21 days but other times one can take much longer than this.

There are also many factors that affect how long your cat will stay in heat; each case is different so make sure you do plenty of research before deciding on what type of veterinary treatment is best suited for your pet.
