Signs of Pregnancy in Cats
The feline gestation period is approximately 63 to 67 days (about 9 weeks).
Early stage (weeks 1–3):
- Nipples turn pink and swell ("pinking up") — visible around 3 weeks after mating
- Vomiting (morning sickness) — occurs in some cats
- Temperament may become calmer
Middle stage (weeks 4–6):
- Abdomen visibly enlarges
- Weight gain of 1–2 kg (2–4 lbs)
- Increased appetite
Late stage (weeks 7–9):
- Belly becomes quite large
- Mammary glands develop further
- Nesting behavior (seeking dark, quiet spots)
- Just before labor: decreased appetite and restlessness
If pregnancy is suspected, visit your veterinarian for confirmation. Ultrasound can detect pregnancy as early as week three.
Caring for a Pregnant Cat
Diet: Switch to kitten food starting in week four of pregnancy. It is higher in calories and protein and supports the demands of nursing as well. See our food guide for recommendations. Increase portions to 1.5 to 2 times the normal amount.
Environment: Provide a quiet, safe space. Discourage vigorous play and jumping from heights.
Vaccines and medications: Consult your vet before administering any vaccines or deworming treatments during pregnancy. Some medications can harm the developing kittens.
Health monitoring: If diarrhea, vaginal bleeding, or lethargy occurs during pregnancy, seek veterinary care immediately.
Preparing for Birth and Newborn Kitten Care
Prepare a nesting box: Line a cardboard box with towels or clean cloths. Set it up in a quiet location 1 to 2 weeks before the expected due date.
The birth process: Labor typically progresses naturally. Delivery of all kittens usually takes several hours to half a day.
Emergency warning signs — call your vet if:
- More than one hour of active labor with no kitten delivered
- Large amounts of green discharge
- The mother cat appears weak or collapsed
- A kitten is partially visible but not progressing
After the kittens are born: Let the mother handle things — she will instinctively sever the umbilical cords, clean each kitten, and begin nursing. Your role is to observe quietly and watch for any abnormalities.
To prevent unplanned pregnancies, discuss spaying with your veterinarian.
Step-by-Step Birth Preparation Guide
Prepare for a safe delivery by completing these essential steps well before the due date.
Step 1: Calculate the expected date. If the mating date is known, count approximately 63–67 days forward. Veterinary ultrasound can provide more precise timing.
Step 2: Set up the nesting box. Place it two weeks before the expected delivery. Line a cardboard box with clean towels in a quiet, dimly lit area. Let the mother cat explore and settle into it beforehand.
Step 3: Confirm emergency contacts. Know your regular vet's after-hours number and the location of the nearest emergency animal hospital before labor begins.
Step 4: Gather supplies. Clean towels, disposable gloves, sterilized scissors (for cutting the umbilical cord if the mother does not), and a kitchen scale for weighing kittens.
Step 5: Prepare the environment. Maintain room temperature at 25–28°C (77–82°F). Eliminate drafts. Keep other pets and children away from the birthing area.
Common Mistakes During Cat Pregnancy and Birth
Avoid these common errors during cat pregnancy and delivery.
Mistake 1: Delaying the diet switch. Transition to kitten food from week four of pregnancy. Regular adult food does not provide sufficient nutrition for the mother and developing kittens.
Mistake 2: Intervening too much during birth. Trust the mother's instincts. Excessive human involvement causes stress and can lead to the mother rejecting her kittens.
Mistake 3: Handling kittens too frequently. Minimize contact during the first few days. An anxious mother may repeatedly relocate her kittens or even abandon them.
Mistake 4: Not planning for [spaying](/en/columns/cat-spay-neuter) afterward. Once nursing ends, discuss spaying with your veterinarian. Repeated pregnancies take a toll on the mother cat's health.
Expert Tips for Cat Pregnancy Care
Veterinary specialists recommend these key practices for managing feline pregnancy.
Nutrition management. Kitten food provides the high-calorie, high-protein nutrition needed during both pregnancy and nursing. Increase portions to 1.5–2 times normal. See our food guide for recommendations.
Timing of X-rays. Radiographs taken after day 40 of pregnancy can confirm the number of kittens, which helps determine during delivery whether all kittens have been born.
Prepare for hand-feeding. Have kitten milk replacer and feeding bottles ready in case the mother cannot nurse. Newborn kittens may need feeding every 2 hours.
Monitor kitten weight daily. Weigh each kitten daily during the first week. A gain of 5–10 g per day is normal. If a kitten is not gaining weight, contact your veterinarian immediately.
When to Consult a Vet During Cat Pregnancy
Seek veterinary care promptly in any of these pregnancy-related situations.
Vaginal bleeding during pregnancy. Any amount of bleeding is abnormal and may indicate miscarriage or placental problems.
Complete [appetite loss](/en/columns/cat-loss-of-appetite). A brief decrease just before labor is normal, but refusing food for more than 24 hours requires evaluation.
Active labor exceeding one hour without delivery. This may indicate dystocia (difficult birth) and a cesarean section may be necessary.
[Lethargy](/en/columns/cat-lethargy) in the mother after delivery. May indicate puerperal fever (uterine infection) or mastitis.
Kittens not nursing. Kittens that do not receive colostrum within the first two hours of life miss critical immune protection. If the mother will not nurse, hand-feeding with kitten milk replacer is essential.
