Have you noticed a change in your unspayed cat’s physical appearance or behavior lately? If so, you might be asking yourself, “Could my cat be pregnant?” and, “What are the signs of a pregnant cat?”
Sometimes it can be hard to tell if a cat is overweight or if they are pregnant. This is likely something you’ve wondered about if your cat is unspayed and able to access the outdoors, where she might come across an unneutered male cat.
There’s an informal checklist that you can go through to help you determine if your cat is pregnant. There are symptoms that occur during the gestation period for cats that can key you into there being something different with their bodies.
Knowing these signs will help you get a clearer picture of what’s going on with your feline. By the way, pregnant cats are called “queens,” which seems pretty fitting to us!
If the thought has crossed your mind, you can always call your veterinarian and set up an appointment to do an ultrasound. For now, learn more about the signs of pregnancy in cats below.
How long is a cat pregnant?
Signs of pregnancy in cats might not begin showing until a few weeks in. The gestation period for cats is typically between 63 and 67 days, which is roughly 9 weeks. If you begin noticing changes in your cat’s appearance or behavior, such as weight gain or sleeping more than usual, it could be an indication of cat pregnancy.
You can always take your cat to the vet as soon as you notice any of these behavioral changes in order to get some confirmation. However, there are more signs and symptoms to look for before bringing your cat in for a vet visit.
What are the physical signs of a pregnant cat?
Your cat’s physical appearance will change as they show signs of pregnancy. The typical things that you might expect, like weight gain and increased sleeping habits, are tell-tale signs, but there are other changes that become apparent as the weeks go by.
Around 3 weeks, the physical changes start to become obvious. It’s at this point that you might begin questioning whether or not your cat is pregnant, how you’ll be as a cat grandparent, or if you should throw your queen a baby shower.
Heat cycles change
Normal heat cycles for cats are somewhere between 10 to 14 days. During their heat cycles, your female cat will often be more affectionate, groom herself more frequently, meow much louder than usual, mark her territory often, and possibly lose her appetite. If the heat cycle suddenly stops, your cat is likely pregnant.
Kittens as young as 4 months can reach sexual maturity and begin their heat cycles. If you do not plan to spay your cat as soon as possible, you can benefit from tracking their cycle to avoid any surprises.
During the length of pregnancy, females will gain 2 to 4 pounds of body weight. Keep an eye on your pet’s weight and make a note of any increases in how much she weighs.
If your cat is simply overweight, you will notice that she gains weight in other parts of her body, like her neck, paws, face, and legs. If she’s pregnant, it’s just her abdomen that will grow, resembling what would be coined as a “pot belly.”
Before your cat begins to eat more than normal, it’s likely that she will experience a decrease in appetite. This might be in response to feelings of nausea while her kittens begin the early stages of their development.
After a few weeks or days of not eating much, you may notice an increase in your cat’s appetite, with her consuming more than she normally would. Reminder: this is because your pregnant cat is eating for more than just herself!
As the kittens grow, she’ll need more nutrients to supplement her body. This will ensure that the kittens are born healthy and developed.
Change in nipple appearance
If your cat is pregnant, you’ll see pink nipples poking out from underneath her fur. You’ll also notice that her nipples look swollen and rosier than usual. Breeders refer to the color change as a process known as “pinking up.”
This “pinking up” is often the first physical sign that will clue you into your cat’s situation. You may even notice some discharge coming from your cat’s nipples, especially as her pregnancy progresses.
Around the halfway point of the gestation period, you’ll notice your cat's belly start to swell. The swelling will start at about 5 weeks into the gestation period up until birth. A swollen stomach could indicate that your pet is pregnant, but the best way to figure it out is to get your cat tested at the vet. This, along with the weight gain, is often enough to understand the new situation you’re about to enter.
Like human mothers-to-be, your cat can experience what you would call morning sickness. Vomiting can be an early sign of pregnancy, too, usually happening around the 3-week mark.
If this happens, check that she’s drinking enough water to stay hydrated. You don’t want her to lose her energy or become sick due to lack of fluids.
However, if the vomiting continues and no other symptoms of pregnancy occur, take your cat to the vet as soon as possible. Vomiting could be a sign of other health-related issues; you will want to get that taken care of.
The best way to know if your cat is pregnant is via ultrasound by a veterinarian. The vet can perform an ultrasound to detect pregnancy as early as 2 weeks. Later in the pregnancy, the vet can also perform an abdomen check and X-rays to see the number of kittens your cat carries.
Behavioral signs of a pregnant cat
Physical changes may not always happen overnight, but personality changes are generally easier to spot. You know your cat best, and if she begins to act abnormally, you’ll probably pick up on it. Sometimes it can be easier to notice the changes in her behavior compared to the physical changes.
To prepare for the delivery of her litter, the soon-to-be mother cat will look for secluded, quiet places to give birth. You might also notice her becoming more territorial with other animals if they threaten to infringe upon her space.
This is a part of the nesting behavior. She will begin to do this only a few weeks before she gives birth, so if you haven’t noticed any changes up until now, it might be time for a veterinarian appointment.
Increased sleep patterns
Being pregnant is a lot of work. It takes up energy, personal nutrients, and resources to create healthy kittens, so don’t be surprised if your cat takes more naps. Your cat will spend more time sleeping when she is pregnant to reserve energy. If you notice your cat napping more often throughout the day, then it’s possible she is pregnant and just resting up.
While your cat might become territorial over her space and toward other animals in the house, she may become more affectionate toward you. Due to hormonal and neurological changes during pregnancy, you may notice your furry friend is seeking your attention more often than usual.
This increase in affectionate behavior can be an indication of pregnancy. She likely trusts you enough to keep her safe and go through the process with you, so be sure to give her all of the attention that she wants.
While increased affection is a common sign early in your cat’s pregnancy, later on you may notice that your cat is more reclusive. In particular, your cat may be more apt to hide or shut herself away in her nesting area the week leading up to labor. She’s preparing for a big moment and knows it, so she may need some space.
Sometimes cats skip this phase and continue to be affectionate and clingy with their humans. You’ll just have to find out!
24 to 48 hours before labor, your cat may show signs of restlessness. These include pacing back and forth, acting fidgety, hovering near her nesting area, and generally showing signs of discomfort. This is her way of letting you know that the time is almost here.
What should I do if my cat is pregnant?
Cats generally manage pregnancy with little difficulty, so there isn’t too much you need to do in the weeks or days leading up to birth. It’s best to keep your vet in the loop, since they are the true experts.
For cats that have regular vet visits and have been pregnant before, a visit to the vet for an official diagnosis might not be necessary since you already know what to expect. Still, your vet is your best resource in keeping your queen content during this stage of life, so do check in.
Here are a few things you can do to keep your cat healthy and comfortable throughout her pregnancy.
Visit the vet
Schedule a visit with your vet as soon as possible. As mentioned earlier, your vet can perform an ultrasound to detect pregnancy as early as 2 weeks. Anywhere between days 17 and 25 of pregnancy, a vet can also perform an abdomen check to feel for kittens in your cat’s womb. Fetal heartbeats are detectable by day 20 of a cat’s gestation period.
Vets can also take X-rays when your cat is further along to determine how many kittens she’s carrying. Kittens’ spines and skulls become visible after 42 days in the womb, so abdomen checks and X-rays are most useful after the 42-day mark.
Wondering how many kittens are in a cat's first litter? First-time pregnancy usually results in smaller litters, but in general, your cat could have anywhere between 1 and 9 kittens!
Maintain a healthy diet
Make sure your cat is eating sufficient amounts of food and drinking lots of water. You may want to switch her over to high-quality, highly-digestible food during pregnancy as well.
Some cat foods are specifically formulated for pregnant cats and are designed to help with both the growth and development of the kittens. These foods are excellent when it comes to providing both the mom and her kittens with all of the nutrients that they need.
Provide a quiet place for nesting
As your cat gets closer to giving birth, she’ll start to look for a quiet and soft place to nest. Cat furniture, large cat beds, or even cardboard boxes lined with towels are great options for pregnant cat moms. She’ll always be safe and cozy with the help of a nesting spot where she can rest, destress, and prepare for her big day!
Keep the litter box clean
Keep a clean litter box for your expecting feline. It will help keep her happy and healthy during her pregnancy. Scoop waste out of the litter box daily and change the litter once or twice a month for optimal happiness and health.
A great way to keep your litter box as sanitary as possible for your pregnant cat is to use a self-cleaning litter box like Litter-Robot, in tandem with pet-friendly cleaner spray or cleaner wipes. You won’t have to worry about scooping and cleaning the box constantly, all while ensuring that your pet has a healthy environment to relieve herself.
Ensure a happy and healthy pregnancy
Treat your pregnant cat like the queen she is by taking the necessary steps to provide the best environment for her throughout the gestation period. Pregnant or not, Litter-Robot and the Whisker app are the perfect pairings for cats in all phases of life.
With Litter-Robot, you’ll get notified when the litter box needs your attention. Plus, you will also be able to monitor your cat’s bathroom behaviors right from your phone.
A final note on spaying cats
While the prospect of having a litter of kittens is exciting, it is highly recommended that you spay your cat after she has healed from giving birth. Spaying your cat is not only better for her overall health, it helps curb feline overpopulation.
