Most cats deliver their kittens without any help at all, and your primary job is to stay calm, keep the environment quiet, and know when something has gone wrong. A normal feline labor can last anywhere from a few hours to over 24 hours for a large litter, and the best thing you can do is prepare the space, observe from a distance, and intervene only when the mother doesn’t do what she’s supposed to.
Signs That Labor Is Starting
In the last 24 hours before labor, your cat will likely stop eating. Her rectal temperature may drop below 100°F (37.8°C), which is the most reliable signal that kittens are coming within a day. You might also notice restlessness, pacing, vocal changes, or repeated trips to her nesting spot. Some cats become unusually clingy, while others want to hide. Both are normal.
This early phase, sometimes called stage one labor, involves uterine contractions that you can’t see from the outside. Your cat may pant, lick her vulva repeatedly, or seem uncomfortable. This stage can last up to 24 hours before active pushing begins. If she goes longer than 24 hours in this restless, uncomfortable state without progressing to visible straining, that warrants a call to your vet.
Setting Up the Birthing Space
A few days before her due date, set up a nesting box in a quiet, low-traffic room. A cardboard box lined with a soft fleece blanket works well. It should be large enough for her to stretch out but small enough to feel enclosed and safe, with sides high enough to keep kittens in but low enough for the mother to step over easily. Keep the room warm: 80 to 85°F is ideal for newborn kittens, who can’t regulate their own body temperature for the first several weeks.
Have these supplies nearby before labor begins: clean towels, unwaxed and unminted dental floss, clean scissors, a bulb syringe, and a small box or basket with a warm towel for kittens if you need to briefly move them. A notepad is useful too, so you can track the time each kitten arrives and whether a placenta followed.
What to Do During Active Delivery
Once your cat starts visibly straining with abdominal contractions, the first kitten should arrive within about an hour. Between kittens, she may rest for anywhere from 10 minutes to over an hour, and some cats pause even longer between deliveries. During these breaks, she’ll typically clean the kittens already born and may eat or drink a little.
For most births, your role is simply to watch. The mother will push each kitten out, tear open the amniotic sac (the thin membrane around the kitten), bite through the umbilical cord, and vigorously lick the kitten to stimulate breathing. She may eat the placentas, which is normal and harmless in small numbers.
Stay quiet and avoid hovering. Too much handling or attention can stress the mother and stall labor. Sit nearby where you can see what’s happening, but resist the urge to touch the kittens unless there’s a clear problem.
When You Need to Step In
There are a few situations where you’ll need to act quickly.
The mother doesn’t remove the sac. If a kitten is born and the mother ignores it for more than a minute or two, you need to clear the membrane yourself. Gently tear it open starting from the face, then use a clean warm towel to briskly rub the kitten’s body, focusing on the muzzle and chest. This rubbing mimics what the mother’s tongue does and stimulates the kitten to start breathing. You should hear a small cry or see movement. If the kitten looks bluish and isn’t breathing well, use a bulb syringe to gently clear fluid from the nose and mouth, then continue rubbing.
The umbilical cord doesn’t separate. Normally the mother chews through it. If she doesn’t, tie a piece of unwaxed dental floss in a tight knot about half an inch from the kitten’s belly, then tie another knot about an inch farther toward the mother. Cut the cord between the two knots with clean scissors. The ties prevent bleeding from either end. Don’t pull on the cord, as it may still be attached to a placenta inside the mother.
A kitten appears stuck. If you can see part of a kitten in the birth canal and the mother has been straining hard for more than 15 to 20 minutes without progress, you can very gently grasp the kitten with a clean towel (never with bare fingers, which are too slippery) and apply slight, steady traction downward in time with contractions. If it doesn’t budge easily, stop and call your vet immediately.
Red Flags That Need a Vet
Not every labor goes smoothly. Difficult labor, called dystocia, happens in a meaningful percentage of cat births and can be life-threatening for both the mother and kittens. Call your veterinarian or an emergency animal hospital if you see any of the following:
- Active straining for more than an hour with no kitten delivered
- More than four hours of intermittent, weak contractions without producing a kitten
- A kitten visibly stuck in the birth canal that you can’t gently free
- Heavy bright red bleeding that doesn’t stop (a small amount of dark or brownish discharge is normal)
- The mother seems extremely exhausted, unresponsive, or is crying in pain between contractions
- A foul-smelling discharge, which can indicate infection
- You know or suspect more kittens remain but labor has completely stopped for more than three to four hours
It’s worth having your vet’s after-hours number saved in your phone before the due date. Dystocia emergencies don’t wait for office hours.
Tracking Placentas
Each kitten should be followed by one placenta, usually within 5 to 15 minutes of that kitten’s birth. Keep count. A retained placenta that stays inside the mother can cause a serious uterine infection called metritis. Signs of this infection include pus-like discharge from the vulva, fever, depression, and the mother neglecting her kittens. If you counted fewer placentas than kittens, or if you notice these signs in the days following birth, contact your vet promptly.
Caring for Kittens Right After Birth
Healthy newborn kittens should begin nursing within the first one to two hours. That early milk, called colostrum, contains antibodies the kittens need for immune protection, and the window for absorbing those antibodies closes within the first day of life. Gently guide a kitten toward a nipple if it seems lost, but most will find their way with minimal help.
If a kitten can’t latch or the mother rejects it, you’ll need to step in with a kitten milk replacer (available at most pet stores) and a small bottle or syringe. Orphaned or rejected kittens need to be fed every two to four hours during their first week of life, including overnight. Keep these kittens especially warm, since they won’t have the mother’s body heat.
Feeding the Mother After Birth
Nursing is the most nutritionally demanding thing your cat’s body will ever do. By the time she’s producing peak milk volume, around three to four weeks postpartum, she needs significantly more calories than normal. During late pregnancy, she should already be eating 25% to 50% more than her usual amount, and that demand only increases once she’s nursing.
Switch her to a kitten formula or “all life stages” food, which is more calorie-dense and nutrient-rich than standard adult cat food. Offer food several times a day or leave it out for free-choice feeding during the first three to four weeks after birth. Make sure she always has easy access to fresh water, since hydration directly affects milk production. Wet food can help boost water intake if she’s not drinking enough on her own. Even with increased feeding, most mothers lose some weight during lactation and gradually return to their pre-pregnancy weight by the time kittens are weaned.
