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.
If your cat was recently in heat and had access to a whole male cat, the likelihood that she is pregnant is very strong. A pregnant queen will display both physical and personality changes which will become more evident around three weeks after breeding. The gestation period for cats runs between 60 to 67 days.
