How Long Are Cats Pregnant? Cats are pregnant for approximately 63 to 65 days, though the length of pregnancy can vary slightly.

Understanding cat pregnancy is essential for proper cat care, especially if you have a pregnant cat.

How Do Cats Get Pregnant?

Cats are mammals, and like other mammals, they reproduce sexually.

Female cats, known as queens, reach sexual maturity and can start going into heat as early as four months old.

During this heat cycle, they can mate with male cats, known as toms. The heat cycle lasts about a week, and if mating occurs, the queen can become pregnant.

The Heat Cycle

The heat cycle, or estrus, is the period when a female cat is fertile and ready to mate.

Signs of a cat in heat include increased vocalization, restlessness, affectionate behavior, and a raised tail.

This cycle can occur every two to three weeks if the cat does not become pregnant.

Fertilization and Conception

During mating, the male cat’s sperm fertilizes the female’s eggs, leading to conception.

The fertilized eggs then implant in the queen’s uterus, where they will develop into kittens over the course of the pregnancy.

Stages of Cat Pregnancy

Cat pregnancy can be divided into three main stages:

  • Early Stage (First Three Weeks): During the early stage of pregnancy, you may notice subtle changes in your cat. She may have a slightly increased appetite and begin to show some behavioral changes, such as increased affection. Her nipples may also become more prominent and pink.
  • Mid Stage (Four to Six Weeks): In the mid stage, the pregnancy becomes more noticeable. The queen’s abdomen will start to swell as the kittens grow. You might also notice increased appetite and weight gain. At this stage, it’s important to provide your cat with high-quality, nutritious food to support her and her developing kittens.
  • Late Stage (Seven to Nine Weeks): During the late stage of pregnancy, the queen will become noticeably larger, and you may even see the kittens moving in her abdomen. She may seek out a quiet, comfortable place to prepare for giving birth. Providing a nesting box with soft bedding can help her feel secure.

Signs of Labor and Delivery

When your cat is close to giving birth, she will show signs of labor. These can include restlessness, nesting behavior, and decreased appetite. Labor is usually divided into three stages:

  • Stage One: The cervix relaxes and contractions begin. The queen may purr, pace, and become more vocal.
  • Stage Two: The kittens are born. This stage can last several hours, especially for first-time mothers.
  • Stage Three: The queen expels the placentas. She will usually clean her kittens and the birthing area.

If you notice any complications during labor, such as prolonged contractions without a kitten being born, contact your veterinarian immediately.

A typical litter size ranges from three to five kittens, but it can vary.

Some cats can have larger or smaller litters depending on their age, health, and breed.

Cat Care During Pregnancy

  • Nutrition: Proper nutrition is crucial during a cat’s pregnancy. High-quality, protein-rich cat food is essential for the health of the queen and her kittens. You may need to increase her food intake as the pregnancy progresses.
  • Veterinary Care: Regular veterinary check-ups are important to monitor the health of the pregnant cat and her kittens. Your vet can provide guidance on proper care and identify any potential issues early on.
  • Comfort and Environment: Ensure your pregnant cat has a comfortable and quiet environment. Provide a nesting box lined with soft, clean bedding where she can feel secure and prepare for labor.

How Can I Tell If My Cat Is Pregnant?

Signs of pregnancy in cats include increased appetite, weight gain, swollen and pink nipples, and a growing abdomen. A veterinary visit can confirm the pregnancy.


Cats are pregnant for approximately 63 to 65 days, during which they undergo several physiological and behavioral changes.

Understanding the stages of cat pregnancy and providing proper care can ensure the health and well-being of both the queen and her kittens.

Always consult with your veterinarian for the best advice and care practices.
