A female cat can get pregnant when sheâs as young as 4 months old, unless sheâs been spayed to prevent that. Queens can keep going into heat every 2 to 3 weeks from the spring through the early fall, making them ready to reproduce more often than not. A catâs pregnancy lasts about 63-65 days.
Gestation. Felines hit puberty and begin mating at about the age of 6 months. A cat's gestation period last approximately 63 days, so if you bred your cat or know when she got out of the house and probably mated you can expect kittens to arrive two months later.
