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.
Length of Gestation. The gestation period usually lasts for approximately 65 days. During this time the female grows larger and larger by day. If a cat is still pregnant after 69 days, it may be time to visit a veterinarian for professional advice. The same action should be taken if the cat begins the birthing process too soon.
