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.
But you may be wondering how old -- or young -- your cat must be in order to have the procedure. You can have a healthy kitten spayed as young as 6 weeks of age in most cases. 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.
