How Long Are Cats Pregnant? Gestation Guide

Cat Gestation Timeline

The cat gestation period is relatively short compared to many other mammals. Understanding the timeline helps you know what to expect and when:

Timeframe	Stage	Key Developments
Days 1-14	Fertilization & Implantation	Eggs fertilized, embryos implant in uterus
Days 15-28	Early Development	Organs begin forming, heartbeat detectable
Days 29-42	Rapid Growth	Skeleton develops, features become defined
Days 43-56	Maturation	Fur grows, kittens gain weight rapidly
Days 57-67	Final Stage	Kittens fully developed, labor approaching

Pregnancy Stages Week by Week

Here's a detailed look at what happens during each week of your cat's pregnancy:

Weeks 1-2: Fertilization

After mating, fertilization occurs within 24-48 hours. The fertilized eggs travel to the uterus where they will implant around day 10-12. During this time, you likely won't notice any physical changes in your cat.

Week 3: Early Signs Appear

The first visible sign of pregnancy is "pinking up" - the nipples become larger and pinker. Some cats may experience morning sickness with occasional vomiting. A vet can confirm pregnancy through palpation or ultrasound at this stage.

Weeks 4-5: Visible Changes

Your cat's belly begins to swell noticeably. Appetite increases as the growing kittens demand more nutrients. This is when you should switch to kitten food for the extra calories and nutrition.

Weeks 6-7: Rapid Growth

The kittens grow rapidly during this period. You may be able to feel kitten movement. Your cat's appetite will continue to increase, and she may eat 1.5 times her normal amount.

Weeks 8-9: Final Preparations

In the final weeks, your cat may start nesting - seeking quiet, comfortable spots for delivery. Her nipples may begin producing milk. She might become more affectionate or alternatively seek solitude.

Did You Know?

Cats can become pregnant again almost immediately after giving birth - sometimes within just 48 hours! This is why spaying is recommended if you don't plan to breed your cat.

Signs Your Cat is Pregnant

Wondering if your cat might be expecting? Look for these telltale signs:

Physical Signs

* Nipples become pink and enlarged (week 2-3)
* Swollen belly (week 4 onwards)
* Weight gain (1-2 kg total)
* Enlarged mammary glands
* Possible morning sickness

Behavioral Signs

* Increased affection
* Nesting behavior
* Increased appetite
* More sleeping than usual
* Heat cycles stop

Prenatal Care for Your Pregnant Cat

Proper care during pregnancy ensures the health of both mother and kittens:

Nutrition

Switch to kitten food: Higher in calories and nutrients needed for pregnancy
Increase portions gradually: By the end of pregnancy, she may eat 50% more
Fresh water always available: Hydration is crucial
Avoid supplements: Unless recommended by your vet
Multiple small meals: Easier to digest as belly grows

Environment

Keep indoors: Protect from injury and disease
Reduce stress: Maintain a calm, quiet environment
Limit handling: Especially of the belly in late pregnancy
Provide comfortable resting spots: Soft beds in quiet areas

Exercise

Light activity is fine and even beneficial, but avoid encouraging jumping or rough play as pregnancy progresses. Let your cat determine her own activity level.

Important: Avoid These During Pregnancy

* Flea treatments (unless vet-approved for pregnant cats)
* Vaccinations (can harm developing kittens)
* Deworming medications (unless prescribed)
* Stressful situations or major changes
* New cats or animals in the home

Preparing for Kittens

As the due date approaches, prepare for the arrival of the kittens:

Create a Nesting Box

Use a large cardboard box with low sides for easy access
Line with clean towels or blankets (avoid loose threads)
Place in a warm, quiet, private location
Keep away from drafts and high-traffic areas
Introduce your cat to it 1-2 weeks before the due date

Supplies to Have Ready

Clean towels and blankets
Kitten milk replacer (emergency backup)
Small scale for weighing kittens
Vet's emergency contact number
Heat pad or lamp (kittens can't regulate temperature)

Signs of Impending Labor

Restlessness and nesting behavior
Loss of appetite (12-24 hours before)
Drop in body temperature
Increased vocalization
Licking of genital area
Visible contractions

When to See the Vet

Regular veterinary care is important during pregnancy. Schedule visits at these times:

When	Purpose
When pregnancy suspected	Confirm pregnancy, initial health check
Weeks 3-4	Ultrasound to count kittens, check development
Week 7-8	Pre-birth check, X-ray to confirm kitten count

Seek Emergency Care If:

* Labor lasts more than 24 hours without kittens
* More than 2 hours between kittens during active labor
* Bloody or foul-smelling discharge
* Extreme lethargy or collapse
* Visible kitten stuck in birth canal for more than 10 minutes
* Fever or signs of infection

Frequently Asked Questions

How long are cats pregnant?▼

Cats are pregnant for approximately 63-67 days, which is about 9 weeks or roughly 2 months. The average gestation period is 65 days from conception to birth. Some cats may deliver a few days early or late, which is typically normal.

What are the first signs of cat pregnancy?▼

Early signs of cat pregnancy include pinking of the nipples (around 2-3 weeks), increased appetite, weight gain, behavioral changes like increased affection, and morning sickness in some cats. A veterinarian can confirm pregnancy through palpation or ultrasound after about 3 weeks.

How many kittens do cats usually have?▼

The average litter size for cats is 4-6 kittens, though this can range from 1 to 12 kittens. First-time mothers and older cats typically have smaller litters. Breed can also influence litter size.

When should I take my pregnant cat to the vet?▼

Take your pregnant cat to the vet as soon as you suspect pregnancy for confirmation and prenatal care advice. Schedule additional visits around weeks 3-4 for an ultrasound, and again at week 7-8 for a health check before delivery. Seek emergency care if you notice discharge, lethargy, or if labor exceeds 24 hours.

What should I feed my pregnant cat?▼

Feed your pregnant cat high-quality kitten food, which has the extra calories and nutrients she needs. Increase food portions gradually, especially in the last few weeks. Ensure fresh water is always available and avoid supplements unless recommended by your vet.

How can I tell when my cat is about to give birth?▼

Signs that labor is approaching include nesting behavior, decreased appetite, restlessness, vocalizing, drop in body temperature, and visible contractions. The cat may seek a quiet, secluded spot. Active labor typically begins within 24 hours of these signs appearing.

The Bottom Line

Cat pregnancy lasts approximately 63-67 days (about 9 weeks). During this time, providing proper nutrition, a stress-free environment, and regular veterinary care ensures the best outcomes for both mother and kittens. Watch for signs of pregnancy, prepare a comfortable nesting area, and know when to seek veterinary help.

If you're not planning to breed your cat, consider spaying to prevent unwanted pregnancies and potential health complications. Consult your veterinarian for personalized advice on caring for your pregnant cat.
