While spaying is traditionally recommended for kitties between 4 and 6 months of age, spaying as young as 8 weeks old is considered safe, according to Cat Channel. Many animal shelters actually spay kitties prior to adopting them out at this age.
On average, cats and dogs are spayed or neutered at between 5 and 9 months of age. Depending upon their size, some puppies and kittens may be safely sterilized when theyâre as young as 8 weeks old. In fact, puppies and kittens recover more quickly from surgery than do adult dogs and cats.
