How Long Are Cats Pregnant?

The average gestation period for cats is about 9 weeks, or approximately 2 months. In days, this typically ranges between 63 and 67 days. However, pregnancies lasting from 58 to 72 days can also be considered normal. If your cat has passed 72 days without giving birth, you should consult your veterinarian immediately.

Cat Pregnancy Stages Week by Week

Your cat's pregnancy can be divided into three main eras (trimesters):

Weeks 1-3: First signs appear. Nipples become pink ("pinking up"), and slight weight gain may occur.
Weeks 4-6: The abdomen becomes noticeably larger, and appetite increases. Kittens' heartbeats can be heard during a vet check-up.
Weeks 7-9: Preparations for birth begin. The mother cat starts nesting, moves more slowly, and milk may leak from her nipples.

What Are the Signs of Cat Pregnancy?

You can observe the following signs to tell if your cat is pregnant:

Nipple Changes: From the 3rd week of pregnancy, nipples turn a dark pink or red color and become enlarged.
Increased Appetite: Pregnant cats require more energy and their appetite increases noticeably.
Abdominal Swelling: From the 5th week onwards, there is distinct swelling and growth in the abdominal area.
Behavioral Changes: Your cat may become more affectionate and attention-seeking, or conversely, more distant. She will start looking for secluded spots due to her "nesting" instinct.
Morning Sickness: Occasional vomiting may be seen in the early stages of pregnancy (weeks 3-4), but consult your vet if it persists.

What to Do When Labor Approaches?

1-2 weeks before birth, the mother cat starts looking for a safe, quiet, and dim place. To support her:

Prepare a "birthing nest" using a cardboard box lined with soft towels or blankets.
Place this nest in a quiet corner of your home.
As birth approaches (about 12-24 hours prior), her body temperature drops, she becomes restless, and constantly grooms her genital area.

When to See a Vet?

If you suspect your cat is pregnant, an ultrasound exam at 3-4 weeks is recommended for a definitive diagnosis and health check. Additionally, seek emergency veterinary care in the following situations:

If the pregnancy duration exceeds 72 days.
If the cat hasn't eaten for more than 24 hours.
If there is foul-smelling or bloody vaginal discharge (except during active labor).
If active straining begins but no kitten is born within 1 hour.
