how soon can a cat get pregnant after having kittens

A cat can get pregnant again as soon as two to four weeks after giving birth, even while still nursing her kittens. Female cats can go into heat and become pregnant very quickly after delivery, often within a few weeks, which means they can have back-to-back litters in a year if not spayed or separated from male cats. However, it is generally recommended to allow some recovery time for the nursing cat before she becomes pregnant again to avoid health risks for her and her kittens.
