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.
1 The average cat pregnancy lasts 65 to 69 days. 2  This may not seem very long, until you take into account the human-to-cat aging ratio. 3  If a cat's yearly age is determined by multiplying seven (a rough estimate, to be sure), then a cat pregnancy is really 14 months long.
