How soon after my cat or dog gives birth can she be spayed?
Ideally, spaying is to be done two weeks to a month after separating (weaning) the kittens/puppies from their mother (queen/bitch) to allow regression of the mammary glands or involution (return to normal size and place) of the uterus. Make sure that your pet will not have a chance to have contact with an intact male (tom/stud) during this period or else there is a possibility that your pet may become pregnant again.
