Can a neutered male cat still get an unspayed female cat pregnant?

Updated On September 23rd, 2025

Pet's info: Cat | American Bobtail | Male | neutered | 28 lbs

Is it possible that a cat that’s been neutered can impregnate a not yet spayed female cat? Because I think that’s what happened here and we are assuming something went wrong when we neutered him 7 years ago.

Hello and thank you for reaching out to Petco Pet Education Center, formerly Petcoach. No, a neutered male cat cannot impregnant a female cat. Neutered males have no testicles and therefore no sperm. If you have a female cat that has become pregnant, she must have been mated by another, intact male cat. I hope this is helpful!

    A truly neutered male can not reproduce with a female. Without testicles they are unable to produce and pass sperm rendering them sterile. Behavior associated with mating can still occur in neutered males however, particularly those which were neutered only recently and may still have residual testosterone circulating in the blood stream.
