How soon after they have a litter can they be fixed?
For dogs, the mother has to stop lactating before we can do surgery. This is typically two weeks after the puppies stop nursing completely. For mother cats, we can do the surgery when the kittens are at least six weeks old. Lactating cats may undergo a flank spay where the reproductive organs are removed though an incision on the side of the abdomen rather than the underside. This minimizes complications that milk production can cause.
