An ovariohysterectomy is often referred to as a spay or spaying. It is a surgical procedure in which the left and right ovary and both left and right horns of the uterus are removed completely, to sterilize or render a female animal infertile. Spaying minimizes the risk of ovarian, uterine, breast, and pituitary gland cancers in rats. Ideally, most rats are spayed between four and six months of age. Complications are rare, but there is a small risk associated with being anesthetized. Most rats will experience no adverse effects and spaying is generally recommended for all healthy, young rats to prevent future health problems.

There are many health and behavioral benefits associated with spaying your rabbit, such as preventing unwanted pregnancies, reducing her risk for reproductive cancers, and minimizing the stress associated with sexual frustration. This handout explains the surgical procedure, post-operative care at home, and, although rare, possible complications that may occur.

Neutering is also referred to as orchidectomy or castration. It is a surgical procedure in which the testicles are removed to sterilize or render a male animal infertile. There are many behavioral and health benefits associated with neutering your rat. Most rats are neutered between four and six months of age.

There are many health and behavioral benefits associated with neutering your rabbit, such as preventing unwanted pregnancies, eliminating his risk for testicular cancer, and minimizing the stress associated with sexual frustration. This handout explains the neuter procedure, post-operative care at home, and, although rare, possible complications that could occur.
