Cat Pregnancy Duration A cat's pregnancy, known as gestation, typically lasts 63-65 days on average, though it can range from 58 to 70 days depending on the breed and litter size.

This equates to about 9 weeks or roughly 2 months , giving owners time to prepare once signs appear around week 3-4.

Key Stages of Pregnancy

Cats experience three trimesters, each about 21 days:

  • Days 1-21 (First Trimester) : Subtle appetite increase; nipples may pinken ("pinking up").
  • Days 22-42 (Second Trimester) : Belly swells, noticeable weight gain, nesting behavior starts.
  • Days 43-65 (Third Trimester) : Milk production, restlessness; kittens often born within 6 hours total.

Signs Your Cat Is Pregnant

  • Physical Changes : Enlarged, pink nipples (2-3 weeks in); rounded abdomen by week 5; weight gain.
  • Behavioral Shifts : Increased affection, more eating (up to double intake), vomiting early on like "morning sickness."
  • Advanced Signs : Nest-seeking, milk leakage near due date.

Care Tips During Pregnancy

  1. Diet : Switch to kitten food for extra calories/protein after vet confirmation.
  1. Vet Check : Ultrasound/x-ray around day 30; deworm/vaccinate pre-pregnancy.
  1. Environment : Quiet nesting box with towels; avoid stress or toxins.
  1. Monitor : Watch for complications like lethargy or discharge—call vet immediately.

Variations and Facts

  • Breed Differences : Siamese/Oriental breeds may go longer (up to 70+ days).
  • Litter Size : 2-5 kittens average; impacts duration slightly.
  • Larger litters can shorten gestation; queens can breed young (5-9 months).
