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.
For many years, veterinarians were taught that cats and dogs had to be a year old to be spayed or neutered. Later, they were taught that six months was appropriate. Today we know that kittens and pups can be spayed or neutered at the age of two months (or two pounds).ne can spay a mother as soon as the kittens or pups are weaned, (5 to 6 weeks for kittens and 4 to 5 weeks for puppies) and because of the risk of pregnancy this should be done.
