What exactly is spay or neuter surgery?
Technically, neutering refers to the removal of the reproductive organs on both male and female companion animals. However, “neutering” is the term commonly used to refer to sterilization of a male by the surgical removal of the testicles. “Spay” is the surgical removal of the ovaries and uterus of a female companion animal. Additional terms that are sometimes used to describe neuter or spay include “alter” and “sterilize”.
