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 vast numbers of cats cared for by shelters and other rescue groups, especially during kitten season, will not drop overnight and will not drop without you. Cats can become pregnant as young as five months of age. Fortunately, kittens as young as two months and weighing two pounds can be safely altered. Many people ask their veterinarian to spay or neuter their pet.
