If you are unaware of cat pregnancy signs, early detection is crucial to managing a healthy cat pregnancy. These signs are included:

• Cat Nipple changes: The cat's nipples will start darkening and swelling around 15 to 18 days.
• Enlarged abdomen and weight gain: The cat will start noticeable weight gain and an enlarged abdomen around the 2 to 3 weeks of pregnancy.
• Cat Behavioral changes: In cat behavior, you will notice cat morning sickness, increased affection, and appetite.

The cat pregnancy normally is about 63 days but can vary in range from 58 to 71 days, so the timeline of the calculator is applied to all broadly domestic cats. Here is the full timeline of cat pregnancy:

• Day 1-14 (Weeks 1-2): Fertilization and the early embryo development. You may not notice any physical changes in the cat, but it is also crucial to start preparing for pregnancy care.
• Day 15-21 (Week 3): Embryos implant in the uterus. Slight weight gain and possibly some nipple colour changes can also be observed.
• Day 22-28 (Week 4): Significant hormonal changes. You will start noticing your cat's increased appetite and morning sickness.
• Day 29-35 (Week 5): The vet can confirm pregnancy through palpation. Embryos are now referred to as fetuses.
• Day 36-42 (Week 6): Visible belly enlargement. Now is a good time for an ultrasound to check the health of the fetuses and estimate litter size.
• Day 43-49 (Week 7): Fetuses grow rapidly, and you may start feeling kitten movements. Increase your cat's food intake as recommended by the vet.
• Day 50-56 (Week 8): Nesting behavior begins. Prepare a quiet, comfortable area for your cat to give birth.
• Day 57-63 (Week 9): Watch for signs of labor, including restlessness and possibly a decreased appetite. Labor could start at any time.

It is super easy: enter your Cat's estimated mating day, and you will see the full timeline week by week and the last delivery day so that you can follow the full timeline to care for the Cat's pregnancy and healthy delivery, so here is the equation equation of Cate's pregnancy: `Cat due date = Mating date + 63 days`

As the pregnancy starts, you need to care for the Cat and gradually increase her nutrition as your vet advises. Make sure that she has a quiet place to rest and that you avoid stressful situations for her.

when the time comes for delivery, you must set up the birthing box in a quiet and warm area two weeks before the expected birth, monitor the Cat for signs of labor, and prepare the vet's contact information.

The Cats are mostly pregnant for about 63 days, but the day can vary from 58 to 71 days.

Yes, you may feel the kittens moving from about the seventh week.

Feed Cat high-quality, nutrient-rich foods, and follow your vet's recommendation to gradually increase her food intake as the pregnancy progresses.

The most accurate way is through palpation, ultrasound, and veterinary examinations.
