Spaying and Neutering Exotic Pets





Catching Up With Dr. Klaphake “Dr. K”
As most of you know Dr. K left AMC at the end of November 2011 to pursue one of his life long passions.  He is currently working as an associate veterinarian at the Cheyenne Mountain Zoo in Colorado Springs, Colorado.  From time-top-time we’d like to share some of his archived articles with you.

Exotic Animal Spays and Neuters by Eric Klaphake, DVM, DABVP (Avian), DACZM
As with dogs and cats, many exotic pets can be neutered or spayed.  Often this can be for the same purposes of dogs and cats for behavior modification, reproduction avoidance, and specific disease prevention. Likewise, spays and neuters are MAJOR surgeries, so anesthetic and surgical complications can occur (though rare), including death. These procedures and post-operative management recommendations need to be taken seriously. We recommend a new pet examination for all exotics, and particularly with rabbits and rodents, this can be helpful to have a professional definitively determine the sex of your pet by examination or more advanced techniques to avoid (or promote) successful reproductive activity.

·         Ferrets—98% of all ferrets in the pet trade are already spayed or neutered and de-scented too. The ones from Marshall Farms have two blue dots tattooed in one ear to indicate this. Other ferrets should be assessed by your exotic animal veterinarian to determine the likelihood of having had the procedure done. Vulvar (reproductive area) swelling in females, less than one year of age, suggests lack of or incomplete spaying and is an immediate health hazard if she is not bred or brought out of cycle. Older females with vulvar swelling suggest adrenal gland disease and need a veterinary visit soon, though it is not an emergency.

·         Rabbits—we recommend all females be spayed due to the high incidence of uterine cancer. Neutering and spaying can also help reduce or avoid behavioral problems. Some testicular cancers have been seen in older rabbits by Dr. Klaphake, but generally are rare.

·         Rats—we recommend neutering to reduce or avoid behavioral problems between males and to avoid unwanted babies. Spaying females at a very early age has been shown to greatly reduce their risk of breast cancer.

·         Guinea Pigs, Chinchillas, Sugar Gliders and other small rodents—we recommend neutering to reduce, or avoid, behavioral problems between males and to avoid unwanted babies. We do not recommend routine spaying, as these are not generally good anesthetic candidates for this longer procedure, since placement of a tracheal tube is usually not possible.

·         Reptiles—the only species we routinely recommend prophylactic spaying in, is Green Iguanas to prevent egg-binding. Neutering male iguanas has helped curb aggression in some individuals but may take time to reach full effect in mature adults; sometimes 1-2 years after surgery. Female turtles are often reported to have egg binding issues in other parts of the country, and world wide, but it does not seem to be an issue in Montana.
