How long are cats pregnant?
Cats are pregnant for around 63–67 days, with most kittens born around day 65. One of the first visible signs is 'pinking up' — the nipples become pink and enlarged about three weeks into the pregnancy.
Use this as an estimate and ask your vet to confirm the pregnancy and check the queen's health.
