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. You may decide that using 63 days as an average gestation period is memorable and easier to equate with human gestation (nine weeks vs nine months).
