Why Do Cats Go Into Heat?

However, in cats, that doesnt necessarily mean ovulation occurs. Cats are induced ovulators, meaning, ovulation happens during the heat only if a female cat has mated the act of breeding stimulates the release of eggs.

Your kitty will meow or yowl very loudly, sometimes referred to as caterwauling. Affectionate or clingy behavior (although some cats will be standoffish). Many of these behaviors, including the yowling, meowing, urinating, and attempts to escape the home, are your kittys efforts to find or attract a mate.

An average cat’s heat cycle can last anywhere from a few days to two weeks. Once estrous cycles begin, cats may go into heat as often as every 2-3 weeks . Breeding season would normally be during warmer weather and longer daylight hours.

To prevent pregnancy, separate your female kitty from any male cats in the household (including blood relatives). This will prevent your kitty from escaping to look for a mate, which will avoid not only pregnancy, but also the risks of getting lost or injured while outside. Its hard for us to know everything that goes on in a cats mind and body, especially since kitties hide their pain well.

A common and serious health risk is called a pyometra, which is an infection that causes the uterus to fill with pus and bacteria, and can lead to a ruptured uterus, shock, and death. Pyometras generally occur after several heat cycles with no mating (due to repeated thickening of the uterine lining), and they require an emergency spay surgery. Fever Vomiting Inappetence Lethargy Pus or other drainage from the vulva

If you notice any of these symptoms (even just one or two of them) within a few weeks after a heat, your kitty needs an immediate veterinary visit. If your cat is showing signs of heat, follow her cues. Remember, her behavior is due to strong hormonal influences that she cant control.

A spay surgery will provide long-term heat and pregnancy prevention, and help your kitty avoid some of the behaviors and health risks that come from hormonal influences.

What triggers a cat to go into heat?

For cats that live outdoors and are exposed to nature on a daily basis, the hormone cycle is triggered by sunlight. Outdoor cats go into heat far more often from spring to fall, when there are more sunlight hours throughout the day. But sunlight isn’t the only cause for a cat going into heat.

Is being in heat painful for cats?

No one can say with any accuracy that heat cycles are painful to cats ; however from the calling (loud yowling) and other symptoms they exhibit, it would appear that they are very uncomfortable. A kitten can have her first heat as early as 4 1/2 months, so don’t fall for that old “wait until six months to spay” advice.

How do you stop a cat in heat from meowing?

The best way to reduce excessive meowing caused by the heat cycle is to have your cat spayed. If your male cat isn’t neutered and he periodically meows excessively, he may be hearing or smelling a female cat in heat. He is likely to pace and meow relentlessly throughout the time the female stays in heat.

A cats first heat happens when she hits puberty at six to 10 months old. Her oestrus cycle will usually last four to five days and, unless she becomes pregnant, she will be in heat again in roughly two to three weeks.

Her inability to relax or get comfortable could be a sign that shes in heat especially if this behaviour is coupled with calling. She may rub up against furniture, doorways and especially your ankles to spread her scent which has changed subtly during this cycle.

Your cat may stick her buttocks in the air and move her tail to one side, which is the mating position. If you dont want to breed your cat, you should have her spayed by your vet to avoid this cycle and the risk of an unwanted or unexpected litter.

Most female cats will go into heat by 6 months of age. But certain environmental factors can cause it to happen more quickly. And certain breedslike Siamesemay go into heat as early as 4 months, while for other breeds 10 months old is a more typical age for going into heat.

Cats have their first estrous (reproductive) cycle when they reach puberty. The estrous cycle is better known as a cat’s heat cycle. On average, puberty, or sexual maturity, first occurs in cats at about six months of age, but this can vary slightly by time of year.

Most cats become very affectionate, even demanding; they persistently rub against their owners (or objects such as furniture), constantly wanting attention. Cats are induced ovulators, which means that the act of breeding stimulates the release of eggs from the ovaries.

The best way to prevent your cat from becoming pregnant is to have her surgically sterilized (an ovariohysterectomy or spay operation) before she has her first estrous cycle. Since it can be difficult to predict when this first cycle will occur, most veterinarians recommend performing an ovariohysterectomy when a cat reaches six months of age.

Signs your cat is in heat

If your cat has not been spayed (neutered/desexed), she will behave differently when she is in heat. Keep an eye out for these behaviours:

1. She is more vocal than normal

Also known as “calling,” your cat may wail, moan or meow more than usual while she is in heat. Her cries may sound distressed – and may even keep you up at night.

2. She’s restless

Her inability to relax or get comfortable could be a sign that she’s in heat – especially if this behaviour is coupled with calling.

3. A low crawl

Your cat may low crawl and moan at the same time if she is in heat. This is normal oestrus behaviour and not a sign that your cat is in pain.

4. Extra affection

She may rub up against furniture, doorways and especially your ankles to spread her scent – which has changed subtly during this cycle.

5. Excessive grooming

During this time, your cat’s genital area will likely become swollen and uncomfortable, which means she might spend more time grooming this area.


When a cat goes into heat, her meow will sound more like a howl and she will be more affectionate toward you, other cats and even the dining room chairs, rubbing against nearly anything and purring loudly. She’ll hold her tail straight up and raise her rear in response to the slightest provocation. She may also spray urine and make a run for the outdoors—in an effort to find a mate—any chance she gets.

How long does estrus last?

Each heat generally lasts several days with the average length being six days. If the queen (an unspayed female cat) is not mated during estrus, she will go out of heat for a short period of time. Therefore, the complete estrous cycle of a cat can range from anywhere between one to six weeks, with the average cycle length being about three weeks.

What are the signs of estrus?

It is not common to observe vaginal bleeding from a cat in heat.Some female cats will urinate more frequently or may even spray urine on vertical objects (Tomcats (unneutered male cats) that have never been seen before in your yard or neighborhood will appear.
