How soon after giving birth can cats get pregnant?
Cats can come into heat and get pregnant again just a few days after giving birth, and this can happen even if they are nursing kittens. But if she did get pregnant with that one “escape” though the vet will still be able to spay her on Tuesday. Many cats are spayed and the owner isn’t even aware that they are pregnant. It’s safe for her, and she’ll be much better off.
