What happens when a female cat which is not spayed and male that neutered get together can they mate?

A spayed female cat has had her ovaries and usually her uterus removed, so she can no longer produce eggs or have kittens. A neutered male cat has had his testicles removed, so he can no longer produce sperm. Therefore, if a spayed female cat and a neutered male cat get together, they will not be able to mate and will be unable to produce kittens.
