Frequently Asked Questions

How long are cats pregnant?

Cats are pregnant for an average of 63-67 days, which is about 9 weeks. However, the gestation period can range from 58 to 72 days, with some variation being completely normal.

How do I calculate my cat's due date?

To calculate your cat's due date, add 63-67 days to the date of first mating. The formula is: Due date = Mating date + 65 days (average). Remember that this gives you an estimated range, not an exact date.

What is 'pinking up' in pregnant cats?

Pinking up refers to when a pregnant cat's nipples become enlarged and turn pink or red in color. This typically occurs around 15-18 days after mating and is one of the earliest visible signs of pregnancy.

How can I tell if my cat is pregnant?

Signs of cat pregnancy include pinking up of nipples (15-18 days), increased appetite, weight gain, enlarged belly (around 30 days), and behavioral changes like increased affection or nesting behavior.

When should I take my pregnant cat to the vet?

Schedule a vet visit around 3-4 weeks after suspected mating for pregnancy confirmation. Regular checkups should continue throughout pregnancy, especially if it extends beyond 72 days.

Can you feel kittens moving in a pregnant cat?

Yes, you can usually feel kittens moving in the later stages of pregnancy, typically after day 50. Gentle palpation of the belly may reveal movement, but always be very careful and consult your vet for proper examination techniques.

What should I prepare for my cat's labor?

Prepare a quiet, warm nesting box with soft blankets in a secluded area. Have your vet's contact information ready, and monitor for signs of labor like restlessness, panting, and seeking secluded spots.
