What Does A Cat Do When They Are In Heat? When a feline enters estrus, commonly known as being “in heat,” they exhibit a range of behaviors. Understanding these signs is essential for cat owners, especially those who haven’t spayed their pet. At solcat.net, we aim to provide you with the knowledge and resources to navigate your cat’s estrus cycle with confidence, ensuring their well-being and preventing unwanted pregnancies. This includes recognizing signs of heat, managing their behavior, and considering spaying as a long-term solution for a happy and healthy feline companion.
1. At What Age Do Cats Start Going into Heat?
Cats typically begin their heat cycles between 5 and 9 months of age. However, some kittens may start as early as 3 to 4 months, while others might not experience their first heat until they are 18 months old. According to veterinarian experts at solcat.net, this timing varies depending on several factors, including the cat’s breed, weight, and the time of year.
2. How Long Does a Cat Stay in Heat?
The feline heat cycle’s length varies and consists of four main stages, as illustrated below:

2.1. Proestrus Stage
Proestrus is the initial stage of a female cat’s heat cycle, marked by increasing estrogen levels. This phase typically lasts one to two days. According to the American Animal Hospital Association (AAHA), symptoms during proestrus are often subtle and may not be noticeable to humans. Male cats might show increased interest, but the female cat won’t be receptive to them at this time.
2.2. Estrus Stage
Estrus is the most noticeable phase of the heat cycle, lasting about a week but potentially ranging from three to 14 days. As feline behavior specialists at solcat.net explain, this stage is what most people refer to when a cat is “in heat.” During estrus, a female cat displays several behavioral changes, such as becoming overly affectionate, vocalizing excessively (also known as “calling”), and acting restless. This is the stage when mating can occur.
2.3. Interestrus or Metestrus Stage
Interestrus and metestrus are intervals that can occur between estrus cycles. Cats are induced ovulators, meaning their ovaries release eggs only after mating with a male cat.
- Metestrus: If a cat in estrus mates, her ovaries release eggs, and the cycle pauses. If these eggs are not fertilized, the metestrus stage lasts 30–40 days. Fertilized eggs result in a pregnancy lasting 60–64 days.
- Interestrus: If a cat in estrus does not mate or release eggs, she enters a one- to three-week interestrus period. During this time, in-heat behaviors decrease, and the cycle restarts at proestrus. Experts at solcat.net emphasize the importance of understanding these stages to manage your cat’s behavior and prevent unwanted pregnancies.
2.4. Anestrus Stage
Cats cycle seasonally, with periods of hormonal inactivity in between active cycles. Anestrus refers to a two- to three-month period without any hormone activity. Veterinarians at the Cornell Feline Health Center note that this period typically occurs during the late fall and winter months when daylight hours are shorter.
3. How Often Do Cats Go Into Heat?
Most cat heat cycles are influenced by the season and daylight hours. As “long-day breeders,” cats experience more frequent heat cycles starting in the spring, peaking from February to April. These cycles often continue until October or November before the anestrus phase begins, unless interrupted by breeding. Solcat.net offers resources and information to help cat owners understand and manage these seasonal cycles.
4. What Are The Key Signs That a Cat Is in Heat?
Unlike dogs and humans, cats do not bleed during their heat cycle; most symptoms observed by pet parents are behavioral. Here are some common signs of a cat in heat:
- Increased Affection: Becoming overwhelmingly affectionate toward humans and other cats.
- Excessive Vocalization: Vocalizing excessively to attract male cats.
- Decreased Appetite: Showing a poor appetite.
- Restlessness: Displaying restless behavior.
- Changes in Urination: Urinating frequently or inappropriately, such as outside the litter box (though these signs are less common).
Many pet parents worry that their cats are in pain due to the intensity of these behavioral changes. According to experts at solcat.net, it’s crucial to consult your vet if your cat experiences sudden behavioral changes to rule out any underlying medical issues.
5. Detailed Look: What Does a Cat Do When They Are in Heat?
When a cat is in heat, her behavior undergoes significant changes driven by hormonal fluctuations. It’s crucial for cat owners to recognize and understand these behaviors to provide appropriate care. Here’s a detailed look at what a cat does when they are in heat, according to veterinary behaviorists at solcat.net:
5.1. Behavioral Changes
5.1.1. Increased Affection and Attention-Seeking
One of the most noticeable changes is an increase in affection. Cats in heat often become extremely cuddly, rubbing against furniture, walls, and their owners more frequently. They may also demand more attention, constantly seeking petting and physical contact.
5.1.2. Excessive Vocalization (Calling)
Cats in heat are known for their distinctive vocalizations, often described as “calling.” This behavior involves loud, persistent meowing, yowling, and caterwauling to attract potential mates. This vocalization can be disruptive and may occur at all hours of the day and night.
5.1.3. Restlessness and Agitation
A cat in heat is typically restless and agitated. She may pace around the house, unable to settle down or relax. This restlessness is driven by the urge to find a mate.
5.1.4. Posturing and Lordosis
A characteristic sign of a cat in heat is a posture known as lordosis. When stroked along the back or near the tail, the cat will lower her frontquarters, raise her hindquarters, and move her tail to the side. This posture exposes her vulva and signals her readiness to mate.
5.1.5. Spraying
Some cats in heat may start spraying urine to mark their territory and signal their availability to male cats. This urine spraying can occur on vertical surfaces around the house and has a distinct, strong odor.

5.1.6. Escape Attempts
Driven by the instinct to find a mate, cats in heat may try to escape from the house. They may dart out of doors or windows when given the opportunity, increasing the risk of getting lost or injured.
5.2. Physical Changes
5.2.1. Swollen Vulva
While not as pronounced as in some other animals, the vulva of a cat in heat may appear slightly swollen and redder than usual.
5.2.2. Vaginal Discharge
In some cases, a cat in heat may have a clear, watery vaginal discharge. However, this is not always present and should not be confused with bleeding, which is abnormal and warrants a vet visit.
5.3. Management Tips
- Keep Her Indoors: To prevent unwanted pregnancies, keep your cat indoors during her heat cycle.
- Provide Comfort: Offer her extra attention and comfort to help her feel more secure.
- Use Calming Products: Consider using calming pheromone products, such as Feliway, to help reduce her stress and anxiety.
- Consult Your Vet: Talk to your vet about spaying your cat, which is the most effective way to prevent heat cycles and unwanted pregnancies.
Understanding what a cat does when they are in heat allows you to provide better care and make informed decisions about your pet’s health and well-being. Solcat.net is committed to offering comprehensive resources to help you navigate every aspect of cat ownership.
6. What Steps Can You Take When Your Cat Is in Heat?
To prevent unwanted pregnancy, female cats should not be allowed outside while cycling. Otherwise, there are no necessary lifestyle changes for cats in heat. If your cat must leave the house while in heat, use a cat backpack or carrier.

If you don’t plan to spay your cat, carefully monitor the length and frequency of estrus behaviors to watch for complications like pseudopregnancy (false pregnancy) or mucometra (mucus in the uterus). Pyometra, or infection of the uterus, is a life-threatening issue. Pyometra can occur at any age but is most commonly seen in middle-aged queens.
Take your cat to the vet if she shows any of the following symptoms during or after her heat cycle:
- Lethargy
- Loss of appetite
- Increased thirst
- Vomiting
- Swollen or painful abdomen
- Pus-like vaginal discharge
7. The Importance of Preventing Heat in Cats
The only way to prevent heat cycles and pregnancy in female cats is to have their uterus and ovaries removed in a spay procedure. Unless your cat is part of an established breeding program, there is no valid reason to leave them intact.
Cats that are not spayed are not only frustrating to deal with due to estrus-related behavior changes, but they are also more prone to pyometra, pseudopregnancy, mammary cancer, and ovarian cancer.
There are currently no known health benefits to allowing your cat to go through a heat cycle before spaying, and it’s recommended to spay your kitten at 5–6 months of age to try to avoid the cycle entirely. For more detailed information and support, visit solcat.net.
8. Understanding the Impact on Male Cats
The presence of a female cat in heat can significantly impact male cats, particularly those who are unneutered. Here’s how male cats typically react to a female in heat:
8.1. Behavioral Changes in Male Cats
8.1.1. Increased Vocalization and Yowling
Unneutered male cats, often referred to as “tomcats,” will become highly vocal when they detect a female cat in heat. They may yowl, meow loudly, and make other distinctive sounds to express their interest and attempt to locate the female.
8.1.2. Restlessness and Pacing
Similar to female cats in heat, male cats become restless and agitated in the presence of a sexually receptive female. They may pace around the house, unable to settle down due to the strong urge to find a mate.
8.1.3. Spraying
Male cats are more likely to spray urine when they sense a female in heat. This behavior is a way of marking their territory and signaling their availability to the female. The urine has a strong, pungent odor that can be very unpleasant.
8.1.4. Escape Attempts
Male cats may try to escape from the house to find a female in heat. They may dart out of doors or windows, increasing their risk of getting lost, injured, or involved in fights with other males.
8.1.5. Aggression
In some cases, male cats may become aggressive towards other cats or even humans due to frustration and heightened hormones. This aggression is more common in unneutered males competing for access to a female in heat.
8.2. Physical Changes in Male Cats
8.2.1. General Agitation
The male cat may exhibit general signs of agitation, such as a tense body posture, dilated pupils, and rapid breathing.
8.3. Management Tips for Male Cats
- Keep Him Indoors: To prevent him from escaping and getting into fights, keep your male cat indoors.
- Neutering: The most effective way to manage these behaviors is to neuter your male cat. Neutering reduces the production of testosterone, which drives many of these behaviors.
- Provide Distractions: Offer him plenty of toys and playtime to help distract him from his urge to find a mate.
- Consult Your Vet: Talk to your vet about neutering your cat and any other concerns you may have about his behavior.
8.4. Neutering Male Cats: Benefits and Considerations
Neutering male cats not only helps to manage their behavior but also offers several health benefits:
- Reduced Risk of Certain Cancers: Neutering reduces the risk of testicular cancer and some prostate problems.
- Decreased Aggression: Neutered males are less likely to be aggressive towards other cats.
- Reduced Spraying: Neutering significantly reduces or eliminates urine spraying.
- Prevention of Unwanted Pregnancies: By neutering your male cat, you prevent him from contributing to the population of unwanted kittens.

9. Beyond the Basics: Advanced Insights into Feline Reproduction
To truly understand what a cat does when they are in heat, it’s helpful to delve into some advanced aspects of feline reproduction.
9.1. Induced Ovulation: The Feline Reproductive Strategy
As mentioned earlier, cats are induced ovulators. This means that the act of mating stimulates the release of eggs from the ovaries. The barbs on a male cat’s penis trigger a hormonal cascade in the female, leading to ovulation. According to research from the Cornell Feline Health Center, this unique reproductive strategy ensures that eggs are released only when mating occurs, maximizing the chances of fertilization.
9.2. The Role of Pheromones in Attracting Mates
Pheromones play a crucial role in feline reproduction. Female cats in heat release pheromones that attract male cats from considerable distances. These chemical signals communicate the female’s reproductive status and readiness to mate.
Male cats also use pheromones to mark their territory and signal their presence to potential mates. Pheromone-based products, like Feliway, can help manage stress and anxiety in cats by mimicking natural feline pheromones.
9.3. Understanding Pseudopregnancy (False Pregnancy) in Cats
In some cases, a female cat may exhibit signs of pregnancy even if she is not actually pregnant. This condition is known as pseudopregnancy or false pregnancy. According to the American Animal Hospital Association (AAHA), pseudopregnancy can occur after a cat has been in heat, even if she has not mated.
Symptoms of pseudopregnancy in cats include:
- Nesting behavior
- Increased appetite
- Weight gain
- Enlarged mammary glands
- Milk production
Pseudopregnancy typically resolves on its own within a few weeks. However, if your cat is showing signs of pseudopregnancy, it’s best to consult your veterinarian to rule out other potential health issues.
9.4. Recognizing and Preventing Pyometra: A Serious Health Risk
Pyometra is a life-threatening infection of the uterus that can occur in unspayed female cats. This condition is more common in older cats but can occur at any age.
Symptoms of pyometra include:
- Lethargy
- Loss of appetite
- Increased thirst
- Vomiting
- Swollen or painful abdomen
- Pus-like vaginal discharge
Pyometra requires prompt veterinary treatment, typically involving surgical removal of the uterus (spaying) and antibiotics. Delaying treatment can be fatal. Spaying your cat eliminates the risk of pyometra.
9.5. The Importance of Early Spaying and Neutering
As mentioned earlier, early spaying and neutering are highly recommended for cats. Spaying before the first heat cycle significantly reduces the risk of mammary cancer, while neutering male cats reduces the risk of certain cancers and behavioral problems.
The American Animal Hospital Association (AAHA) recommends spaying or neutering kittens at 5–6 months of age. Early spaying and neutering have numerous health and behavioral benefits and help control the pet population.
