Frequently Asked Questions
How long is a cat pregnant?
Cats are pregnant for approximately 63-67 days (about 9 weeks), with an average of 65 days from mating to birth. Kittens born before day 58 are considered premature and may need veterinary intervention. If pregnancy extends beyond 70 days, contact your veterinarian.
How many kittens are in a typical litter?
The average litter size is 3-5 kittens, though litters of 1-12 are possible. First-time mothers and older cats tend to have smaller litters. Siamese and oriental breeds often have larger litters. An ultrasound at day 20-25 or X-ray after day 45 can help estimate litter size.
What are the first signs of cat pregnancy?
The earliest visible sign is 'pinking up' of the nipples at around days 15-18, where they become pinker and slightly enlarged. Other early signs include increased appetite, mild morning sickness, increased affection, and slight weight gain. A veterinarian can confirm pregnancy by palpation at day 20-25.
