How Long Are Cats Pregnant for in Weeks?

A cat pregnancy lasts roughly 9 weeks.

Here’s a quick look:

• Week 1–2: Early development begins
  
• Week 3–4: Physical changes start
  
• Week 5–6: Belly grows noticeably
  
• Week 7–8: Kittens develop quickly
  
• Week 9: Labor can begin
  

Some cats may give birth a little early (around day 60) or slightly later (up to day 67). Both can still be normal.

If you searched “how long are cat pregnant,” the correct term is still the same — about 63 to 65 days total.

How Long Are Cats Pregnant in Months?

In months, cats are pregnant for a little over 2 months.

It’s shorter than humans, which makes it feel fast. One day you may not notice anything. A few weeks later, kittens are on the way.

Because it’s such a short timeline, it’s important to pay attention early.

Early Signs Your Cat Is Pregnant

Many US pet owners first notice small behavior changes. Here are common early signs:

• Nipples become pink and slightly larger (around week 3)
  
• Increased appetite
  
• Sleeping more
  
• Gentle weight gain
  
• More affection (sometimes the opposite)
  

By week 5, the belly usually becomes rounder.

If you live in warmer states like Florida or Arizona, where outdoor cats are common, pregnancies can happen often during breeding seasons.

If you suspect pregnancy, a vet can confirm it around 2–3 weeks in using an exam or ultrasound.

Cat Pregnancy Timeline (Simple Breakdown)

Let’s go week by week in a way that’s easy to understand.

Weeks 1–2

Fertilization happens. No visible changes yet.

Week 3

Hormones shift. Nipples may turn pink. Mild nausea can occur.

Week 4

Embryos grow quickly. A vet may feel small changes.

Week 5

The belly becomes noticeable. Weight gain increases.

Week 6

Kittens develop organs and bones. You might feel movement.

Week 7

Mother cat may start nesting behavior.

Week 8

Milk production may begin. Restlessness increases.

Week 9

Labor usually starts. She may look for a quiet, safe space.

How Many Kittens Do Cats Usually Have?

The average litter size is 3 to 5 kittens.

First-time mothers may have fewer. Some breeds have more. Larger litters are common in healthy adult cats.

Your vet can often estimate litter size through ultrasound or X-ray later in pregnancy.

What to Do During Your Cat’s Pregnancy

If your cat is pregnant, here’s what helps:

1. Provide High-Quality Food

Switch to kitten food. It has more calories and nutrients.

2. Keep Stress Low

Avoid loud changes at home. Give her a quiet resting space.

3. Schedule a Vet Visit

Even indoor cats in cities like New York or Chicago need checkups during pregnancy.

4. Prepare a Nesting Area

Use a soft box with blankets. Keep it warm and private.

How Do You Know Labor Is Starting?

Close to birth, you may notice:

• Restlessness
  
• Pacing
  
• Heavy breathing
  
• Refusal to eat
  
• Drop in body temperature
  

Labor usually starts within 24 hours after these signs appear.

If strong contractions last more than an hour without a kitten being born, call your vet.

When to Call a Vet

Seek help if:

• Pregnancy lasts longer than 67 days
  
• There is green discharge before a kitten arrives
  
• Your cat seems in distress
  
• A kitten gets stuck
  

Most births go smoothly. But having a vet number ready is smart.

Common Question: Can Indoor Cats Get Pregnant?

Yes. If they are not spayed and have access to male cats, pregnancy is possible.

Even indoor cats may escape briefly. Spaying is the only way to fully prevent pregnancy.

In the US, many shelters strongly encourage spaying to reduce unwanted litters.
