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 research shows that healthy kittens can be safely neutered at 6 weeks, or as soon as they weigh 2 pounds. Referred to as early-age, pediatric, or pre-pubertal spay/neuter, the procedure eliminates any chance of an âoops litter,â since female cats can become pregnant as young as 4 months of age.
