You’ve noticed something different about your cat lately. She’s been acting a little off. Maybe she’s gained some weight, or she’s been extra affectionate, or she’s been spending a lot of time in dark, quiet corners of your house. And suddenly, the thought hits you: is my cat pregnant?
If your cat isn’t spayed and has access to male cats (even just a quick encounter), pregnancy is definitely possible. And if you’re not sure whether your cat is pregnant, you’re not alone. Cat pregnancy can be tricky to spot, especially in the early stages. Some signs are obvious. Others are subtle and easy to miss or confuse with other health issues.
This guide walks you through everything you need to know about identifying cat pregnancy, what to expect, and how to care for your pregnant cat.
The Basics: How Cat Pregnancy Works
Before we talk about the signs, let’s cover some basic facts about cat pregnancy. Understanding how it works will help you recognize the signs when you see them.
How Long Is a Cat Pregnancy?
Cat pregnancy lasts about 63 to 67 days, or roughly nine weeks. That’s shorter than human pregnancy but longer than you might expect. It’s a relatively quick process, which means if your cat is pregnant, you’ll know fairly soon.
How Many Kittens Will She Have?
Most cats have between three and five kittens per litter, though some have as few as one or as many as eight or more. The number depends on the cat’s age, health, genetics, and whether it’s her first litter.
When Can Cats Get Pregnant?
Cats can get pregnant as early as four months old, though it’s more common in cats six months and older. They go into heat (estrus) multiple times a year, usually in spring and summer, though indoor cats can go into heat year-round. If your cat has access to a male cat during heat, pregnancy is very likely.
Early Signs of Cat Pregnancy (Weeks 1-3)
The first few weeks of cat pregnancy can be subtle. Your cat might not show obvious signs, or the signs might be easy to miss or confuse with other things. Here’s what to look for:
Behavioral Changes
One of the earliest signs of pregnancy is a change in behavior. Your cat might become:
- More affectionate: Some pregnant cats become clingy and want more attention and cuddles. They might follow you around more than usual or seek out your lap.
- Less affectionate: Other cats become withdrawn or irritable. They might want to be left alone more than usual.
- More vocal: Some pregnant cats meow more frequently or sound different.
- Restless: Your cat might seem unable to settle down, constantly changing positions or moving between rooms.
These behavioral changes happen because of hormonal shifts. Your cat’s body is preparing for pregnancy, and those hormones affect her mood and personality.
Changes in Appetite
In the early weeks, some cats experience nausea similar to morning sickness in humans. Your cat might:
- Eat less than usual
- Be picky about food
- Vomit occasionally
- Show less interest in treats she normally loves
This usually passes by the second or third week. After that, most pregnant cats actually eat more as their bodies demand extra calories to support the growing kittens.
Nipple Changes
One of the most reliable early signs of pregnancy is changes to the nipples. Around week two or three, your cat’s nipples will become:
- Larger and more prominent
- Darker in color (they’ll go from pink to a deeper pink or reddish color)
- More sensitive (your cat might not like them being touched)
This happens because her body is preparing to nurse kittens. If you gently lift your cat’s fur and look at her nipples, this change is usually pretty obvious.
Middle Signs of Cat Pregnancy (Weeks 4-6)
By the middle of pregnancy, the signs become much more obvious. Your cat’s body is changing noticeably, and her behavior continues to shift.
Weight Gain and Belly Growth
Around week four, you’ll start to see physical changes. Your cat will gain weight, and her belly will start to round out. By week five or six, the weight gain is usually pretty obvious. She might look like she’s eaten a big meal that she can’t digest.
The weight gain isn’t just from the kittens. It’s also from increased body fat, fluid, and the placenta. A pregnant cat might gain two to four pounds over the course of her pregnancy.
Increased Appetite
After the early nausea passes, most pregnant cats develop a serious appetite. She might eat 25-50% more than usual. This is normal and necessary. Her body needs extra calories to support the growing kittens and to prepare for nursing.
Make sure you’re feeding her high-quality, nutrient-dense food. Consider switching to kitten food if you haven’t already—it has more calories and nutrients that pregnant cats need.
Behavioral Nesting
As pregnancy progresses, your cat might start showing nesting behaviors. She might:
- Spend more time in dark, quiet, enclosed spaces
- Rearrange bedding or blankets
- Seek out closets, under beds, or other secluded spots
- Become protective of certain areas of your home
This is instinctive. Your cat is preparing a safe place to give birth and raise her kittens. It’s a good sign that her pregnancy is progressing normally.
Increased Affection or Irritability
Some pregnant cats become extra cuddly and want constant attention. Others become more irritable and want to be left alone. Both are normal. Your cat is dealing with hormonal changes and physical discomfort, and her personality might shift accordingly.
Late Signs of Cat Pregnancy (Weeks 7-9)
In the final weeks of pregnancy, the signs are unmistakable. Your cat is clearly pregnant, and you’re probably counting down the days until the kittens arrive.
Obvious Belly Enlargement
By the last few weeks, your cat’s belly is noticeably enlarged. You might even be able to see or feel the kittens moving inside her belly. If you gently place your hand on her side, you might feel small lumps or movement. Don’t poke or prod too much—she’s uncomfortable enough already.
Visible Kittens Moving
In the final weeks, you might actually see the kittens moving under your cat’s skin. Her belly might ripple or shift as the kittens move around. It’s kind of amazing to watch, honestly.
Decreased Activity
Your cat is carrying extra weight and dealing with physical discomfort. She’ll probably move more slowly, rest more often, and be less interested in playing or jumping. This is completely normal. She’s conserving energy for labor and delivery.
Milk Production
In the final week or two before delivery, your cat’s nipples might start leaking milk. This is a sign that her body is preparing to nurse. If you see milk on her nipples or on her bedding, labor is probably coming soon.
Restlessness and Nesting Intensifies
As labor approaches, your cat will become increasingly restless. She’ll spend more time in her chosen nesting spot, rearranging blankets and getting comfortable. She might meow more, seem anxious, or pace around. These are all signs that labor is coming soon—probably within 24-48 hours.
Temperature Drop
About 12-24 hours before labor, your cat’s body temperature will drop from her normal 101-102°F to around 99°F or lower. If you have a thermometer and want to monitor this, you can take her temperature rectally. A drop below 99°F usually means labor is imminent.
How to Confirm Pregnancy: Vet Visit
If you suspect your cat is pregnant but aren’t sure, the best thing to do is take her to the vet. Your vet can confirm pregnancy and give you important information about what to expect.
When to Visit the Vet
If you think your cat might be pregnant, schedule a vet visit as soon as possible. Early confirmation is helpful so you can start preparing and making sure your cat gets the right nutrition and care.
How Vets Confirm Pregnancy
Your vet can confirm pregnancy through:
- Physical examination: Palpation (gently feeling the belly) can detect pregnancy as early as week three or four.
- Ultrasound: This is the most reliable way to confirm pregnancy and can be done as early as week two. It also shows how many kittens your cat is carrying.
- X-rays: In the later stages of pregnancy (week six or seven), X-rays can show the kittens’ skeletons and give an accurate count of how many are coming.
What Your Vet Will Tell You
During your vet visit, your vet will:
- Confirm that your cat is pregnant
- Estimate how far along she is
- Give you advice on nutrition and care
- Check for any health issues that might complicate pregnancy
- Discuss what to expect during labor and delivery
- Answer any questions you have
This is valuable information. If there are any complications or concerns, your vet can catch them early.
Caring for Your Pregnant Cat
Once you know your cat is pregnant, there are specific things you should do to support her health and prepare for the kittens.
Nutrition
Pregnant cats need more calories and nutrients than non-pregnant cats. Here’s what to do:
- Switch to kitten food: Kitten food is higher in calories and nutrients. It’s designed for growing bodies, which is exactly what your pregnant cat needs.
- Feed more frequently: Instead of one or two meals a day, offer food multiple times throughout the day. Pregnant cats have smaller stomachs (because the kittens are taking up space), so they do better with smaller, more frequent meals.
- Increase portion sizes: By the end of pregnancy, your cat might be eating 25-50% more than usual. Let her eat as much as she wants.
- Provide fresh water: Pregnant cats need more water. Make sure fresh water is always available.
- Consider supplements: Talk to your vet about whether your cat needs any supplements. Some vets recommend prenatal vitamins.
Prepare a Nesting Area
Your cat will need a safe, quiet place to give birth and raise her kittens. Here’s how to set it up:
- Choose a quiet location: Pick a room or closet that’s away from high-traffic areas and noise.
- Set up a nesting box: A cardboard box, plastic storage container, or pet bed works well. Line it with clean blankets or towels.
- Make it accessible: Your cat should be able to get in and out easily, but it should be enclosed enough that she feels safe.
- Keep it clean: Change the bedding regularly and keep the area clean.
- Let her choose: Your cat might have her own ideas about where she wants to nest. If she chooses a different spot, that’s okay. You can set up a nesting box there instead.
Limit Strenuous Activity
As your cat gets further along in pregnancy, she’ll naturally slow down. Don’t force her to play or jump. Let her rest as much as she needs. Avoid picking her up or handling her roughly, especially in the later stages of pregnancy.
Keep Her Indoors
If your cat has outdoor access, keep her indoors during pregnancy. She’s vulnerable, and you want to make sure she stays safe and doesn’t go into labor somewhere you can’t help her.
Monitor Her Health
Watch for any signs of complications:
- Excessive vomiting or loss of appetite
- Discharge from the vulva (other than clear fluid)
- Lethargy or extreme weakness
- Difficulty moving or obvious pain
- Fever or signs of illness
If you notice any of these signs, contact your vet immediately. Complications during pregnancy are rare, but they can happen.
What to Expect During Labor and Delivery
Labor usually lasts 2-6 hours, though it can take longer. Here’s what to expect:
Signs Labor Is Starting
- Your cat becomes very restless and anxious
- She might refuse to eat
- She’ll spend time in her nesting box, getting comfortable
- She might meow or cry more than usual
- Her body temperature has dropped (if you’ve been monitoring it)
- You might see clear fluid or a mucus plug
The Delivery Process
Once active labor starts, your cat will begin having contractions. She might:
- Strain and push
- Meow or cry out
- Lick her vulva frequently
- Change positions frequently
Kittens are usually born 15-30 minutes apart. Your cat will deliver each kitten, then the placenta. She’ll instinctively clean the kitten and chew through the umbilical cord.
When to Call the Vet
Call your vet immediately if:
- Your cat has been in active labor for more than 2 hours with no kitten delivered
- More than 3 hours pass between kittens
- Your cat is straining hard but nothing is coming out
- There’s green or black discharge before the first kitten is born
- Your cat seems to be in severe pain or distress
- A kitten is partially delivered but stuck
These could be signs of complications that need immediate veterinary attention.
After Birth: Caring for Mom and Kittens
Once the kittens are born, your job isn’t over. Your cat and her new babies need care and monitoring.
Let Mom Do Her Thing
In the first few hours and days after birth, let your cat focus on her kittens. She’ll clean them, nurse them, and bond with them. Minimize handling and visitors. Your cat needs to focus on her babies without stress or distraction.
Monitor Nursing
Make sure all the kittens are nursing. They should be latching onto the nipples and feeding regularly. If a kitten seems weak or isn’t nursing, contact your vet. Bottle feeding might be necessary.
Provide Extra Food and Water
A nursing cat needs even more calories and water than a pregnant cat. She’s producing milk for her kittens, which is demanding on her body. Keep food and water bowls nearby so she can eat and drink without leaving her babies for long.
- Continue feeding kitten food
- Offer food multiple times a day
- Make sure fresh water is always available
- Some cats lose weight while nursing, which is normal
Keep the Nesting Area Clean
Change bedding regularly to keep the nesting area clean and dry. Wet or dirty bedding can lead to infection or make the kittens uncomfortable. But do this gently and quickly so you’re not stressing out your cat.
Watch for Signs of Complications
After birth, watch for signs that something isn’t right:
- Mastitis: Swollen, hard, or painful nipples. Your cat might have a fever or seem lethargic.
- Retained placenta: If your cat delivered fewer placentas than kittens, one might be retained. Signs include discharge, fever, or lethargy.
- Eclampsia: A dangerous condition caused by low calcium. Signs include restlessness, stiffness, muscle twitching, or seizures.
- Infection: Fever, lethargy, loss of appetite, or foul-smelling discharge.
If you notice any of these signs, contact your vet immediately. Post-birth complications can be serious.
Vet Checkup
Schedule a vet checkup for your cat about 24-48 hours after birth. Your vet will make sure she’s recovering well and that there are no complications. They’ll also check the kittens to make sure they’re healthy.
Special Situations
Your Cat Is Young (Under One Year)
If your cat got pregnant as a kitten or young cat, she’s at higher risk for complications. Young cats’ bodies aren’t fully developed, and pregnancy can be harder on them. Make sure she gets excellent nutrition and regular vet care. After she gives birth, consider having her spayed to prevent future pregnancies until she’s older.
Your Cat Is Older (Over Five Years)
Older cats can get pregnant, but pregnancy is riskier for them. They might have underlying health issues that complicate pregnancy. Make sure your older pregnant cat gets regular vet checkups and excellent care. Be prepared for the possibility of complications.
Your Cat Has Health Issues
If your cat has diabetes, heart disease, kidney disease, or other health conditions, pregnancy can be risky. Talk to your vet about whether it’s safe for her to continue the pregnancy. In some cases, spaying might be recommended to prevent future pregnancies.
You Can’t Care for the Kittens
If you’re not prepared to care for a litter of kittens, or if you can’t afford the vet care, talk to your vet or a local animal rescue. They might be able to help you find homes for the kittens or provide resources. Don’t feel guilty—it’s better to ask for help than to struggle alone.
Prevention: Why Spaying Is Important
If you don’t want your cat to get pregnant again, spaying is the best option. Spaying (ovariohysterectomy) is a surgical procedure that removes the uterus and ovaries, preventing pregnancy.
Benefits of Spaying
- Prevents unwanted pregnancies
- Eliminates heat cycles (and the associated behaviors and stress)
- Reduces the risk of certain cancers and infections
- Can improve behavior (reduces roaming, aggression, and excessive vocalization)
- Prevents overpopulation (there are millions of cats in shelters)
When to Spay
The best time to spay is before your cat’s first heat cycle, usually around 4-6 months old. However, cats can be spayed at any age. If your cat is currently nursing, wait until the kittens are weaned (usually around 8 weeks old) before spaying.
Cost and Recovery
Spaying costs vary depending on your location and vet, but it typically ranges from $200-$500. Recovery takes about 10-14 days. Your cat will need to rest, avoid strenuous activity, and have her incision checked regularly.
If cost is a concern, many animal shelters and rescue organizations offer low-cost spaying services.
The Emotional Side of Cat Pregnancy
Watching your cat go through pregnancy and birth is an emotional experience. You might feel excited, nervous, overwhelmed, or all of the above. That’s completely normal.
Remember that your cat is experiencing something major too. Pregnancy and birth are physically and emotionally demanding. Be patient with her. Give her the space and support she needs. And don’t be surprised if your feelings about the whole experience are complicated.
Some people find the experience beautiful and meaningful. Others find it stressful and wish they’d spayed their cat earlier. Both reactions are valid.
The Bottom Line
Cat pregnancy lasts about nine weeks, and the signs progress from subtle to obvious over that time. Early signs include behavioral changes, nipple changes, and nausea. Middle-stage signs include weight gain and increased appetite. Late-stage signs include obvious belly enlargement, decreased activity, and nesting behaviors.
If you suspect your cat is pregnant, take her to the vet for confirmation. Once pregnancy is confirmed, focus on nutrition, creating a safe nesting space, and monitoring her health. Be prepared for labor and delivery, and know when to call the vet if something seems wrong.
Most cat pregnancies and births go smoothly without complications. But it’s important to be informed and prepared. Your cat is counting on you to help her through this major life event.
And if you don’t want to go through this again, spaying is a safe, effective way to prevent future pregnancies. It’s one of the best things you can do for your cat’s long-term health and well-being.
