Stages of Cat Pregnancy

Mother cat and kitten

Spaying and neutering cats is a common part of good pet ownership. Spaying not only reduces the number of undesirable cats, but it also protects your own cat from disorders that affect the reproductive system, such as breast cancer and uterine infections. Understanding the phases of pregnancy can guarantee a healthy gestation time for both mom and her kittens if you find yourself caring for a pregnant cat, regardless of whether the breeding was deliberate.

Fertilization

A cat must first be receptive to mating in order to conceive, which occurs during estrus, or when cats are "in heat." Heat cycles in an unspayed cat can begin as early as 4 months of age and peak between February and April in the Northern Hemisphere, however they can last into the late fall in certain circumstances. When your cat is in estrus, she is ready to mate and will be receptive to males for seven days, however this might vary substantially. Your cat will be lot more loud and loving during this period. Your cat may also pee more often or leave urine marks on items. Mating does not have to be scheduled to a specific ovulation event since cats are "induced ovulators," which means mating encourages their ovaries to produce eggs that can be fertilized.

There are multiple processes involved in fertilizing a cat's egg (ovum). A zygote is formed when sperm and egg combine. The embryo next goes through many rounds of cell division to generate the first cells that will give rise to all of the embryo's components. Each step marks a new stage in the development of the embryo. Two weeks after conception, the embryo is implanted in the uterine lining. Embryos are implanted in an even pattern along the uterine horns.

Embryo Development

As the embryos develop, cells migrate and specialize to generate the progenitors of all the body's components. The skin and nervous system, as well as the digestive organs and the rest of the organs, begin as three different layers of cells. The placenta begins to develop at the moment of implantation and permits the mother and fetus to exchange nutrients and waste products. Each embryo has its own placenta and amniotic sac. By the third week of pregnancy, they have grown to around 2.5 cm in diameter and may be felt by an expert veterinarian during a physical exam.

Your cat will gain weight and increase her food consumption throughout the first month of pregnancy as the embryos develop. Your cat's nipples may get enlarged and darker in color as the pregnancy proceeds, and she may exhibit behavioral changes like as symptoms of nesting. It's critical to feed high-quality cat food that's designated for pregnant cats or kitten food that's higher in nutrients and calories.

Ongoing Gestation and Labor

Your queen will show indications of approaching labor as she approaches her due date (about nine weeks following fertilization, or 65 days after mating). This involves nesting—snooping around in closets and isolated corners for a suitable location to give birth to her kittens and bringing soft things into her selected spot to create a warm, soft nesting environment. It's a good idea for you to assist with setting up a box or basket with soft towels or other safe sleeping materials in a secluded, quiet location.

Your cat's main goal from now until birth will be to develop the fetuses, which will take a lot of her body's energy. Make sure you offer a high-quality pregnant cat food or a higher-calorie kitten food. She should also be kept indoors with as little stress as possible.

Another symptom of approaching labor is increased love. Your cat may crave constant contact with you. Behavioral changes like as restlessness, pacing, panting, nesting behavior, continual purring, and being aggressive toward strangers and other cats are other signals that your cat is going to give birth.

About 24 to 48 hours before birth, your cat may have milky discharge coming from her nipples. This indicates "go time"—kittens are on their way.

When labor starts, it normally moves quickly, with all of the kittens being born in 6-8 hours. The mother should birth kittens every 60 minutes or fewer until all of them are born. If she continues to push for more than 60 minutes without delivering a kitten, there may be a problem, and you should contact your veterinarian immediately. Because cats might temporarily halt their labor if they are anxious, it is critical to provide them with a secure, peaceful environment and as much solitude as possible. There would be no pushing if labor was interrupted, therefore this would be different from a cat pushing unsuccessfully.

Pregnant Cat Care

If you have a pregnant cat, take her to the doctor right away for a "well-check." Discuss additional preventative health procedures that are vital and safe for a pregnant cat, such as FIV (Feline Immunodeficiency Virus) and FelV (Feline Leukemia Virus) tests.

Assuming your cat is healthy, effective pregnancy care includes a high-nutrient food as well as fresh, clean water. In addition, your cat should be kept at all times. Switch your pregnant cat to premium-quality or a food indicated for pregnant and nursing cats throughout pregnancy, and keep her on this diet until the kittens are weaned.

Potential Problems

Pregnancy and delivery complications are uncommon, but they can be significant. As a result, having the phone number and location of the nearest emergency veterinary facility on hand is critical.

Any unexpected symptoms should be followed up with a phone or visit to your veterinarian during pregnancy. This is a crucial aspect of a pregnant cat's care. Although many pregnant cats have a trouble-free pregnancy, there are certain issues that might arise. Learn how to recognize the signs of difficulty and what steps to take to protect a and her babies. The following are a few conditions to be aware of so that you can recognize symptoms and take appropriate action if they occur.

Eclampsia

Eclampsia, a life-threatening illness caused by calcium deficiency, most commonly occurs when the kittens are one to four weeks old and the mother is producing the most milk. It can even happen before the baby is born. Any pregnant or nursing cats that exhibit any of these symptoms should seek medical attention immediately. Calcium supplements and supportive care are part of the treatment. It can get more severe in subsequent pregnancies, so bear that in mind.

Signs of Eclampsia in Pregnant Cats

  • Behavioral Symptoms: Restlessness, pacing, and panting.
  • Physical Symptoms: Stiffness in gait, trouble walking, twitching, seizures, and muscle spasms.

Eclampsia is a veterinary emergency, and the cat should be seen immediately by a veterinarian at the first signs of symptoms.

Spontaneous Abortion

A pregnant cat's poor health, particularly some illnesses, might lead to sudden abortion. If this occurs early in the pregnancy, the embryos are simply reabsorbed by the mother's body, with no symptoms. Fever, bleeding or green discharge from the vaginal area, and sadness are all possible symptoms.

After a spontaneous abortion, your cat will need to be monitored carefully. The cat should be examined in case there are additional fetuses, alive or dead, or signs of a uterine infection.

Resorption

Early in pregnancy, a deceased embryo is totally absorbed by the queen's system, which is an intriguing phenomena. When resorption happens, there are seldom any visible indications. Because there are generally several kittens in a litter, you may never notice because the rest of the kittens will be born normally. A veterinarian visit is required if fewer kittens than expected were delivered, to confirm that there are no leftover fetuses within the queen.

Dystocia

The term "dystocia" refers to difficulties giving delivery. Dystocia occurs when a cat in labor continues to push for more than an hour without giving birth to a kitten. Dystocia can be caused by a variety of factors, including very big or tiny litters, older queens, abnormally large kittens, or congenital defects in one or more kittens. If you believe more than an hour has gone between delivery, contact your veterinarian immediately. A C-section may be required in some situations to rescue both the mother and the kittens.

If you suspect your pet is sick, call your vet immediately. For health-related questions, always consult your veterinarian, as they have examined your pet, know the pet's health history, and can make the best recommendations for your pet.
