If your cat is expecting kittens, you might be wondering, “How long are cats pregnant for in weeks?” Understanding your cat’s pregnancy timeline helps you care for her properly and prepare for the arrival of her kittens.
How Long Are Cats Pregnant For?
On average, a cat’s pregnancy lasts around 9 weeks, or roughly 63 to 67 days. In weeks, that’s about 8 to 9 weeks total.
However, depending on the cat’s health, breed, and environment, the pregnancy might last anywhere between 58 to 72 days.
Cat Pregnancy Timeline (Week-by-Week)
Let’s break it down to understand what happens during each stage of your cat’s pregnancy:
Week 1–2: Fertilization and Early Growth
After mating, the fertilized eggs travel to the uterus and implant. During this stage, you might not notice any visible changes — your cat behaves normally.
Week 3–4: Signs of Pregnancy Appear
The embryos develop quickly. Around the third week, your cat’s nipples may become pink and enlarged — this is known as “pinking up.”
She may also start to eat more or less and might experience morning sickness similar to humans.
Week 5–6: Belly Starts to Show
Your cat’s abdomen will begin to swell as the kittens grow. Her appetite will increase significantly. During this time, ensure she’s eating high-quality kitten food for extra nutrients.
Week 7–8: Nesting Behavior Begins
As labor approaches, your cat may look for a quiet, warm place to give birth — known as “nesting.” You might notice her licking her belly more and becoming restless.
Week 9: Labor and Birth
By the 9th week (around day 63), your cat is ready to deliver. She might stop eating and meow more frequently before labor begins. Labor usually starts with restlessness, followed by contractions and kitten delivery.
How to Tell If Your Cat Is Pregnant
Here are some common signs of pregnancy in cats:
-
Swollen or pink nipples
-
Weight gain
-
Rounded belly
-
Increased affection or sometimes irritability
-
More frequent grooming
-
Seeking quiet spaces
A vet can confirm pregnancy with an ultrasound or X-ray, usually around the third week.
How to Care for a Pregnant Cat
Proper care helps ensure both the mother cat and her kittens stay healthy. Here’s what to do:
-
Feed nutritious food: Switch to high-protein kitten food.
-
Provide a calm environment: Keep her stress-free and comfortable.
-
Regular vet checkups: Monitor her and the kittens’ health.
-
Prepare a nesting box: A cardboard box lined with soft blankets works well.
-
Avoid unnecessary handling: Especially during the last few weeks.
When to Call the Vet
Call your vet immediately if your pregnant cat:
-
Goes over 70 days without giving birth
-
Has bloody discharge before labor
-
Seems in pain for hours without delivering a kitten
-
Has difficulty breathing or extreme weakness
