What is the Youngest Age My Pet Can Be Spayed or Neutered?
While there is no conclusive proof of an age, current research indicates that spaying before the first heat can prevent the development of tumors in the mammary glands. Female kittens can go into heat as early as four months and therefore are candidates for spaying at that time. Neutering puppies and kittens is currently done on animals who are six to eight weeks and weigh at least two pounds.
Many people obtain their pets when they are have grown a bit more, so this is not often a factor. However, the earlier you spay or neuter the faster and less stressful to the animal. There is less body fat, bleeding is minimal, and they awaken much faster after surgery. They can be fed and sent home the same day.
