How long are cats pregnant?
The average feline gestation is 64 days, but anything from 61 to 72 days can be normal. Cats are induced ovulators, so mating does not guarantee pregnancy, and the exact ovulation date is often unknown.
A vet can confirm pregnancy with an ultrasound from about day 16-25. Later in pregnancy, X-rays can help estimate the number of kittens.
A simple care timeline
Keep your cat indoors from the time she may be pregnant. Provide a quiet nesting box by week five, and switch to a kitten or growth diet as her appetite and energy needs increase. Avoid flea products and medications unless your vet confirms they are safe in pregnancy.
- Week 1-3: confirm with your vet; keep her indoors.
- Week 4-5: appetite rises; set up a nesting box in a quiet room.
- Week 6-7: X-ray can estimate kitten count; limit rough handling.
- Week 8-9: watch for nesting, restlessness and appetite changes.
When labour needs help
Call your vet if labour lasts more than 2-3 hours between kittens, if a kitten is stuck in the birth canal, if she strains for more than 20-30 minutes without delivering, or if she is bleeding heavily. Kittens are usually born 10-60 minutes apart, though longer gaps can occur.
This tool supports planning, not breeding decisions. Spaying is the safest option for most cats, and breeding should only happen with health screening and homes lined up beforehand.
