The American Animal Hospital Association supports the concept of neutering cats and dogs as young as 8 weeks of age in order to help reduce the overpopulation problems in companion animals.
Veterinarians are encouraged to counsel their clients about responsible breeding and to spay or neuter their pets before they have an unwanted litter. Practitioners should make recommendations based on an assessment of each individual patient.
Adopted by the American Animal Hospital Association Board of Directors, November 1994. Last revised March 2010.
