Cats in heat, commonly known as the feline heat cycle, go through a natural stage in a female cat’s reproductive life. In this guide, we’ll explain what it means when a cat is in heat, how to spot the typical signs my cat is in heat, and when it’s best to consult your vet.
What Does It Mean When a Cat Is in Heat?
The term “in heat,” or oestrus, refers to the phase in an unspayed female cat’s cycle when it is ready to mate. Despite the name, being “in heat” has nothing to do with body temperature or heatstroke—it’s all about hormonal changes and mating behavior.
When will my cat be in heat?
A female cat typically enters her first heat cycle around 6 months of age, though this can vary slightly between individuals, with some starting as early as 5 months. This marks the beginning of the ability to reproduce; if not desexed, it can become pregnant during this time. Unlike females, male cats (toms) do not go into heat, but they can detect and actively respond to a female in heat through their natural mating behavior.
Cats are seasonally polyestrous, which means they can go into heat multiple times throughout the breeding season. If a female mates during this time, she may become pregnant—often more than once per season. These cats are highly fertile; a single queen can have two litters per season, each with 3 to 5 kittens or more, leading to an estimated 100–200 kittens over her lifetime if not desexed.
Signs Your Kitten Is in Heat
When a kitten is in heat, you might hear lots of loud meowing or crying, especially at night. The kitten will act extra friendly and rub against furniture or your legs more than usual. You’ll notice the kitten sticking its rear end up in the air with the tail moved to one side.
The kitten might try to run outside to find other cats and may spray strong-smelling pee around your home. Your pet might not eat as much food and could seem unable to relax. These behaviors usually last about a week and will happen again every few weeks if the kitten isn’t fixed.

How To Tell If Your Kitten Is In Heat?
Your kitten might be in heat if it meows loudly day and night. The kitten will act super friendly, rubbing against everything and wanting lots of pets. You’ll see your kitten lift its back end up high when touched. The kitten might try to sneak outside whenever doors open.
Look for small amounts of blood spots where the kitten sits. Your pet might mark territory by peeing in odd places around the house. The kitten won’t sit still for long and might seem stressed out. These signs show up every few weeks until your kitten gets fixed at the vet.
How to know if my kitten is in heat?
You can tell your kitten is in heat when they start making weird crying noises all day and night. They get super clingy and rub against your legs and furniture way more than usual. When you pet their back, they stick their butt up in the air with their tail moved to the side. Your kitten might try to dash out the door every chance they get. You might spot tiny blood drops where they’ve been sitting.
They might pee in strange places around the house with a really strong smell. Your poor kitty will seem restless and might not eat much. These behaviors usually last about a week and keep coming back every few weeks until you get them fixed.
Cats typically stay in heat for about 5 to 7 days, though the duration can vary. Some are in heat for just 2 days, while others may remain in heat for up to 19 days. During this time, the queen (female cat) will show clear behavioral signs of being ready to mate.
If a female cat doesn’t mate with a male cat, it will go out of heat for a short period, usually around 8 to 9 days, though this break can differ. After this pause, she’ll enter another heat cycle. These cycles of going in and out of heat continue until the cat either gets pregnant or is spayed.

- Adopting a crouched posture with front legs low, hindquarters raised, and tail to the side to expose the vulva
- Frequently rolling on the floor Loud, persistent vocalizing to attract male cats.
- Displaying restlessness or bursts of hyperactive behavior
- Showing extra affection toward people
- Eating less than usual
- Spraying urine or marking furniture and other items
- Eagerly trying to get outdoors
1) Your cat is more vocal (louder)
One of the most noticeable signs—seen in both male and female cats is excessive meowing or yowling. When in heat, cats often become unusually vocal, making sounds that may resemble crying or even yelling. Though it might seem like your cat is distressed, this loud meowing is actually a mating call. If your cat is already chatty by nature, it can be tricky to tell, so it’s worth watching for other signs of heat as well.
2) Your cat is spraying
While spraying is more common in males, some unspayed female cats do it too, even if they’re using their litter box regularly. During heat, spraying helps mark territory and acts as a scent-based signal to attract mates. It’s their way of saying, “I’m available,” to any potential feline visitors.
3) Your cat seems restless
A cat in heat may pace around, sleep less, and spend more time near windows where they can see or sense other cats. This kind of restlessness, especially when paired with loud meowing, is another strong clue your cat is going through a heat cycle. They just can’t seem to get comfortable or sit still for long.
4) Cat needs extra affection
A cat in heat, especially females, becomes affectionate. They nuzzle your legs, rub their cheeks against you, and wind their tails around your ankles. This behavior, along with vocal mating calls, is a strong indicator your cat is in heat.
5) Your cat is low-crawling around the house
If your cat is suddenly slinking close to the ground, especially near corners or along walls, and mewing softly while rubbing her cheeks on furniture or walls, she’s likely in estrus. Though it might appear to be in discomfort, this behavior is a natural way for a cat in heat to spread her scent to attract potential mates.
6) Grooming more than usual
When in heat, a female cat often grooms excessively around her belly and genital area. This increased grooming helps soothe the mild swelling of her genitalia during estrus, offering her a bit of relief from the hormonal changes.
7) Your indoor cat is eager to explore the outdoors
A patched cat with a white muzzle, chest, and paws may seem inside, but the instinct to roam—especially during heat can be strong. If your cat isn’t spayed, it constantly tries to sneak outside in search of a mate. Letting indoor cats wander freely poses serious safety risks, from traffic to fights with other animals. To avoid unwanted pregnancies and roaming behavior, it’s best to have your cat neutered or keep her indoors until her heat cycle passes.
8) Your cat is raising its rear end
One of the most noticeable signs of a female cat in heat is her posture, keeping her front low, often shifting its tail to the side to expose her genital area. This behavior signals readiness to mate and is instinctively inviting attention from male cats.
How to Calm a Cat in Heat?
If you notice the signs my cat is in heat, you have to take some steps.
1. Create a Calm Environment
Set up a quiet, cozy space with a soft bed or blanket. Keep making less noise and reduce any distractions that might create stress.
2. Reduce Stimulation
Turn off the lights, close the curtains, and avoid sudden movements or orsft sounds to help them relax.
3. Offer Hiding Spots
Give her access to cardboard boxes or enclosed beds where the cat can feel safe and secure.
4. Provide Vertical Climbing Options
Cat trees, wall shelves, or window perches allow them to climb and explore, which can ease restlessness.

Avoid over-petting or touching sensitive areas like her lower back and belly, which may overstimulate and cause aggression.

A heated pad or warm, soft bed can comfort your cat by relaxing muscles and soothing its discomfort.

Interactive toys like feather wands, puzzle feeders, or laser pointers redirect energy and help to tire out.

Gentle classical music or nature sounds can create a peaceful environment that helps to settle down.
