How This Happened in the First Place: Baby Girl Grows up
Many people are surprised to find that the feline reproductive system is seasonal. Cats are designed to give birth only during warm months (spring through early fall). While not every female cat follows this rule to the letter, in general, cats are reproductively inactive when the days are short, and they begin their hormonal cycles annually when they perceive the days to be getting longer.
The female cat begins cycling when she has reached 80% of her adult size and when the days are appropriately long. This could be as young as four months of age. After age seven or eight years, cycles become irregular, and there are more complications with birth, so it is important to finish a female cat’s breeding career before this time.
Indoor cats are sheltered from the light cycles of the sun and may not cycle as frequently as their outdoor counterparts. On the other hand, breeders who keep their cats completely indoors can manipulate the light cycle of the cattery so as to allow for year-round cycling if desired.
Proestrus
This is the time in the cycle when the female begins attracting males but is not yet receptive to their advances. Estrogen is building up, and she is preparing for ovulation. The female is extra affectionate at this time, rubbing her head and sticking her rump in the air. She may also urine mark in the house and vocalize loudly and frequently. This period may be as short as 12 hours and as long as two days.
Estrus
The female cat’s behavior continues: rubbing, crying, etc., but the difference here is that the male is accepted when he approaches. This behavior persists for approximately seven days (on average), and during that time, the female’s behavior is often objectionable to the owner. Contrary to previous belief, the act of mating does not shorten the estrus period (though it does substantially lengthen the time before the next estrus period). The female cat is ready to ovulate at this time but, in general, will not do so unless a male cat breeds her.
Interestrous Period
This is the period between times of behavioral estrus. If the cat is not bred or is bred and fails to ovulate, this time period is eight to 10 days on average. This means that the yowling, rubbing, urine marking, and other estrous behaviors continue for about a week, then discontinue for about a week, then begin again, back and forth all spring and summer and into the fall until the cat is either bred, spayed, or perceives the coming of winter. This behavior of the mature female cat is often all the motivation it takes for an owner to get her spayed, even if she is completely confined indoors and has no chance of unwanted pregnancy.
Diestrus
If the female is bred and ovulates, she goes into this different reproductive stage. Her ovaries prepare for possible pregnancy, and she will stay out of heat for at least 35 to 37 days even if she is not pregnant. If she is pregnant, she will carry her kittens for 64 to 66 days before delivering the litter. If, for some reason, spaying is desired but must be delayed, and yet the estrous behavior is driving the owner crazy, the cat may be fooled into thinking she has been bred through manipulation with a rectal thermometer. If you are interested in this procedure, contact your veterinarian as it is not as simple as it may sound but is often effective in providing peace at home.
How this Happened in the First Place, Part 2: The Lovers
The lovers. Image courtesy of Dr. Teri Ann Oursler.The female cat in estrus is a flirtatious creature. She seeks territory that has been urine-marked by the male of her choice. (If the breeding is planned, it is generally best to bring the female to the male’s territory to approximate the natural situation.) She approaches the male, rubbing, nuzzling, etc. If she is in a receptive period of her cycle, she will allow him to bite the nape of her neck and will give him about 30 seconds to complete his sexual act. She typically yowls loudly during this time. The female immediately becomes refractory and attacks the male, who backs off to wait for another chance. The female reaction to breeding involves obsessive rolling around on the ground and vaginal licking. After a few minutes, she is ready for more and will indicate this by rubbing on him or patting gently at him. With each breeding, the time until the next attempt grows longer but may continue all day long.
Diagnosis of Pregnancy
The owner may notice that the unspayed female is rounder than usual and that her nipples have become prominent (called pinking up). This may not be noticeable until well into advanced pregnancy, depending on how observant the owner is, how large the litter is, etc. There are several ways to confirm feline pregnancy.
Blood Test
The Witness Pregnancy Test is approved for both canine and feline use and can be performed in about 15 minutes at your veterinarian’s office. She must be about 30 to 35 days into the pregnancy for this.
Ultrasound
Ultrasound can readily confirm pregnancy at approximately 22-25 days of pregnancy but is not readily available in all animal hospitals. Ultrasound cannot accurately determine how many kittens to expect, and this is important information best obtained with a radiograph later on. Ultrasound can, however, be used to determine the delivery date for the kittens by measuring the head and body.
Radiology
At about 45 days of pregnancy, the kittens will have mineralized their skeletons and be visible on an x-ray. This is the only procedure that reliably can determine how many kittens to expect.
Palpation
Some veterinarians can feel the developing kittens between days 17 and 25.
Care During Pregnancy
The female cat has relatively few needs during pregnancy. She will need a food that is approved for growth (i.e., a food appropriate for kittens) as she will need the extra calories, particularly after delivery when she is nursing. Her metabolic demand during nursing will triple, and she will especially need the extra calories then.
Flea control is important during pregnancy as flea anemia is one of the leading causes of death in neonatal kittens. Find an appropriate flea product approved for use in feline pregnancy.
Do not vaccinate a pregnant cat.
Hopefully, her vaccinations were current prior to pregnancy. Developing kittens are vulnerable to live viruses used in modified live virus vaccinations, feline distemper in particular. The female cat, either infected in pregnancy or vaccinated with live virus during pregnancy, can produce kittens with a specific birth defect called cerebellar hypoplasia, a brain malformation that leads to tremors and wobbling, particularly when the cat is attempting a specific task (the so-called “intention tremor.”)
Most mother cats will seek their own nesting area in the last week or so of pregnancy. If you wish to help her, expect her to require soft bedding, an area with minimal human traffic, and separation from other pets in the home.
Labor
Several hours (and perhaps a whole day) of restlessness, grooming, nesting, pacing, panting, vomiting, and crying indicates that labor has begun. Like the dog, there is often a drop in body temperature (to less than 99 degrees F), indicating contractions will commence in the next 12 to 36 hours but this is not as reliable a finding as in the female dog. The female cat secludes herself in her selected nest area and begins to purr.
The above first stage of labor progresses to the second stage of labor with the initiation of hard contractions and the birth of a kitten. The third stage of labor refers to the passing of the placenta. The entire litter is born usually within six hours, with kittens every 30 to 60 minutes. If she is stressed or distracted, she is able to stop her labor and restart the next day. The new mother usually eats the placenta and membranes of the kitten’s sac. There is no special benefit to this behavior, so if you wish, you may remove these tissues from the nest and prevent her from eating them, but if you plan to cut the umbilical cord so as to disconnect the kitten from the placenta, be careful not to tug on the umbilical cord as this can damage the baby's internal organs. Do not attempt to move her and the kittens to a “better” nest spot after labor has started. This may stress her into curtailing her labor or, worse may scare her into neglecting the litter.
Strong contractions for more than 60 minutes without producing a kitten indicate she needs help and should see the veterinarian right away.
Most of the time, labor is normal and goes off without a hitch. Kittens may begin eating solid food around age four weeks of age and may be adopted to new homes at age eight weeks.
Vaginal discharge is normal for up to three weeks postpartum. This discharge is typically black or reddish and consists mostly of old blood. If the discharge seems particularly bloody, have the veterinarian assess her blood loss. If the discharge looks like pus, she may have a uterine infection. Bring her to the veterinarian; she may need to be spayed right away.
Complications Surrounding Labor and Pregnancy
Vaginal Bleeding
Vaginal bleeding during pregnancy is not normal and suggests that she is aborting the litter. If this is occurring late in pregnancy (the eighth week), she may be delivering the litter prematurely, and a cesarean section is likely necessary. In either case, have the veterinarian check her to assess the blood loss and decide what to do.
Dystocia
If she has been having strong contractions for more than 60 minutes, she needs assistance in passing the kitten. Bring her and any kittens delivered to the veterinarian’s office right away.
Retained Placenta/Metritis
If the mother cat retains the placenta, she can develop an infection, fever, or appetite loss, and neglect the kittens. If this occurs, she will need to see the veterinarian right away, possibly be hospitalized, and will probably need to be spayed to remove the infection.
Neonatal Isoerythrolysis
If the mother cat has Type B blood and the kittens have Type A blood, antibodies in the mother's milk will destroy the kitten's red blood cells. This is only preventable if you know the mother’s blood type in advance (most cats are Type A, but certain breeds commonly have Type B blood). Kittens in this situation can be saved if they do not nurse from their natural mother. See more information about neonatal isoerythrolysis.
Getting her Spayed at Last
Many people are surprised by their cat’s pregnancy and do not really want the kittens, but since she is pregnant, choose to go ahead with the litter, intending to spay her when the kittens are weaned. The female cat may have other plans. Nursing the litter generally suppresses the return to cycling, but the average female cat is back in heat about a month after delivery of the litter. If she has access to a male cat, she will likely become pregnant before she is finished weaning the current litter.

The reason for this is to allow the mammary tissue to dry up and go back to a more normal, less vascular state. Spaying the female while her glands are still full leads to more bleeding and more difficult surgery. If the choice comes down to spaying her with mammary development versus having an unwanted litter, however, spaying is a better choice.
Raising Orphans
Sometimes, you are faced with a litter that is too large for one mother cat to handle, or disaster may strike, leaving the kittens motherless. See full instructions on what to get and do in order to successfully raise a litter of orphan kittens.
When the Mother Cat is Feral
Local feral cat sterilization programs commonly involve removing the tip of an ear to designate a cat as neutered. Image courtesy of MarVistaVetA feral animal is a member of a domestic species (such as a cat) who is living wild. If kittens are captured prior to age 10 weeks, they can usually be tamed and become normally socialized to human contact. After this age, socialization is much more challenging. Feral adult cats are often best left living in the wild world despite its hazards. This does not mean that they should be allowed to freely reproduce, however. “Trap-Neuter-Release" (TNR) is a program that allows for humane management of a feral cat colony and has become official policy in many communities. For information on how to care for a feral cat colony appropriately, contact your local animal regulation department for feral cat groups in your area.

Difficult Birth: First Aid
Roger Gfeller, DVM, DACVECC; Michael Thomas, DVM; Isaac Mayo;The VIN Emergency Medicine Consultants

Puppies are born 58 to 72 days after mating. Because canine spermatozoa live 4 to 11 days in the bitch’s reproductive tract, it is usually not possible to accurately determine the day of birth from the time of mating. If purposefully breeding, ovulation timing can be performed to determine with much greater accuracy the expected delivery date. A cat’s gestation period is similar at 63 to 65 days.
If the contractions are frequent, regular, and strong, and no young is produced in 15 to 30 minutes, the pet should be taken to a veterinarian. Intermittent contractions with no kitten or puppy should be evaluated after 1.5 to 2 hours as long as the dam appears comfortable. A dark green vaginal discharge called lochia should be followed within 5 to 10 minutes by a puppy or kitten, but only before the first one. Heavy bleeding requires an immediate veterinary examination.
While a few cats can take up to 24 hours to complete the birthing process, most should follow the same protocol as for dogs.
About two out of three cases of difficult birth (known as dystocia) that need to be seen by a veterinarian will need to have an emergency C-section performed. It is good practice to know long before the due date where your local veterinary emergency facility is, and when and if they can perform a C-section. C-sections are risky and expensive surgeries and careful consideration should be given to the decision to breed your pet or not. X-rays taken after the 44th day of gestation (not necessarily from breeding) can show how many babies will be born but they are much easier to count when the skeletons are fully mineralized later in gestation, after day 50. This will allow you to know when the mother is done giving birth.
Reddish to brownish vaginal discharge can continue for several weeks after a normal birth. If the mother is eating normally and is normally active, this isn’t a problem. If she becomes lethargic, stops eating, has a fever or acts ill, prompt veterinary attention is needed.
Some new mothers can experience a condition called eclampsia in which their blood calcium levels drop dangerously low. This is due to the large amount of calcium secreted in milk for newborns. Dogs with eclampsia experience poor mothering, severe muscle tremors, difficulty walking, and seizures. Immediate veterinary care is needed if your dog is showing any of these signs. Eclampsia can happen anytime around birth but is most common during peak milk production (2 to 4 weeks after birth).

What to Do
- Prepare a clean, warm, and easy-to-clean area for the birth. Puppy rails for whelping boxes are lifesavers for puppies.
- Check on the mother frequently without disturbing the process. Repeated interruptions will only delay birth.
- If a baby is visible in the birth canal and appears stuck, gently grasp the foot or feet with a clean cloth. With a steady motion gently pull upwards towards the dam’s tail on the baby only when the female is contracting. If the baby does not come out easily, transport the pet to a veterinarian.
- When the baby is born, it will likely be covered in a membrane. If the mother doesn't remove it, tear this membrane and remove it from the baby’s head region.
- If the mother doesn't remove the umbilical cord, or is being rough with it, tie it with a piece of string or dental floss one-fourth of an inch from the baby's abdomen. Then cut the cord one half of an inch from the abdomen with a sharp scissor on the dam’s side of the cord. Apply 2 percent tincture of iodine to the entire umbilicus (buy this beforehand, just in case).
- Keep the babies warm. It is best to leave them with their mother, but sometimes she doesn't stay with them. In that instance, put a plastic bottle filled with warm water near the babies. A hot water bottle covered with a towel works as does a Snuggle Safe™ disc. Neonates must have room and be strong enough to move away from the heat source. The room temperature should be around 85F. Allow room for the babies to move toward or away from the heat source.
- Do not put your fingers in the birth canal as you can cause trauma or infection.
- Do not forcibly attempt to remove a baby.
- Do not assist delivery by pulling on the head of a baby or on the umbilical cord as it exits the mother.
- Do not lift the baby by the umbilical cord.
- Do not use a heating pad.
- Most kitten and puppy births go smoothly with the mother doing all the work. The babies contentedly nurse on the mother soon after birth.
- You may not see the afterbirth (placenta) being passed. Many mothers will eat this after it is passed without anyone noticing. It’s usually not a problem if all of the placentas are not immediately passed as the dam usually passes them later, but on occasion retained placentas do not pass and in those cases can cause serious illness.
