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.
The Correct or Ideal Age. The Cat Health Guide recommends having female kittens spayed by the time they are 6 months old. The Cat Care Clinic of Orange County, California, says kittens can be spayed at 8 weeks but recommends waiting until 4 months to 6 months of age. Nevertheless, kittens can be spayed as young as 6 weeks.
