Heat in Female Cats

Written by Antoinet | May 20, 2025

Heat is the period during which a female cat is fertile. During this phase, she exhibits noticeable behavioral changes such as loud, plaintive meowing, restlessness, and an increased need for attention. Her body is preparing for possible mating with a tomcat, and her hormones are thrown out of balance.

At What Age Does a Cat Go Into Heat?

Most cats begin their first heat cycle between the ages of 5 and 9 months. However, this depends on the breed. Oriental breeds often go into heat earlier, while Persian cats, for example, tend to experience it later. Indoor cats may start their cycle a bit later compared to outdoor cats, as seasonal influences like daylight play a role in triggering heat.

How Long Does a Cat Stay in Heat?

On average, a cat is in heat for 4 to 7 days. If she is not mated during this period, she may return to heat after a short rest. This cycle can occur several times a year, especially in unspayed females.

How Often Does a Cat Go Into Heat?

Cats can go into heat multiple times per year. During the warmer months, when the days are longer, a cat can go into heat as often as every two to three weeks. Indoor cats may experience more frequent heat cycles, as they are less affected by changes in daylight.

How Can You Tell if a Cat Is in Heat?

There are several signs that indicate a cat is in heat. She may meow more than usual, behave differently, and become extra affectionate. You might notice her lifting her tail, often arching her back slightly, and assuming unusual positions to attract male cats.

A common question is: do cats bleed when they are in heat? Normally, there is no blood discharge during a cat’s heat cycle. Some cats may have a small amount of clear discharge. If your cat is bleeding or has abnormal discharge, you should contact your veterinarian.

What Can You Do if Your Cat Is Struggling with Heat?

If your cat’s heat cycle causes discomfort or behavioural problems, there are several steps you can take. First and foremost, it’s important to provide her with as much calm and a safe environment as possible. Always keep her indoors to prevent unwanted mating.

There are supplements available that can help regulate hormone balance. This may reduce the frequency of heat cycles. One example is Puur Oestro.

Don’t want kittens in the future? Then have your cat spayed. A female cat ovulates when she mates, meaning every successful mating can lead to pregnancy and a litter of kittens.

Prefer not to spay or want a litter in the future? Then you could consider the cat contraceptive pill. Be aware, however, that this pill carries potential health risks. Other options you can discuss with your veterinarian include a neutering implant (castration chip) or a SHAM mating (non-fertile mating to suppress heat).

Finally, giving your cat extra attention, playtime and mental stimulation can help make this period more manageable for both of you.
