A brother and sister from the same litter can create their own litters by the age of five months. It is not a good idea to allow this to happen. Mother cats or dogs can become pregnant while nursing. It is important to keep a nursing mother away from other adult cats/dogs of the opposite sex. One can spay a mother as soon as the kittens or pups are weaned, (5 to 6 weeks for kittens and 4 to 5 weeks for puppies) and because of the risk of pregnancy this should be done.
Most kittens can be safely spayed or neutered at the age of six weeks, by a vet familiar with early spay/neuter techniques. If you have no such a vet locally, consider asking for a spay/neuter deposit, to be refunded when the adopter of a kitten presents evidence the S/N has been done.
