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.
You won't have to wait very long for your next litter of kittens to be born, although it may take a couple weeks before you can confirm that your cat is indeed expecting. Feline pregnancy lasts anywhere from 57 to 67 days, although it may at first be difficult to tell if a cat is actually pregnant. One obvious sign is that her estrus cycle ends. Her body will then begin changing in anticipation of the birth of her kittens. First, her nipples will begin to turn pink or a rosy color.
