There is a way of chemically castrating dogs which is being called, “Zeutering”. The made up word comes from a chemical that is injected into the testes of dogs which neuters them because it destroys the sperm producing cells. The chemical is called Zeuterin™. It is also called zinc neutering.
Chemical castration is used on dogs at the SPCA of Central Florida. As far as I can tell, Colombia is the only country who chemically castrate their cats using this product. Perhaps chemical castration will be used on domestic and feral cats in America in due course.
Zeuterin™ is the first FDA approved injectable product for sterilizing dogs of 3 -10 months of age. The solution is injected into each of the dogs testes with a very fine needle. The procedure is very straightforward and fast and the dog is sedated mildly prior to the injection. There is a 99.6% excess rate and sterilization is permanent and irreversible. Dogs can go home immediately after the injections. The procedure is cheaper than surgery and shorter and therefore there will be savings on cost. This should be particularly attractive at animal shelters.
Apparently, each injection saves at least $25 per dog. If one million surgical neuters were carried out using this chemical instead, it is argued that animal welfare groups as a whole could save $50 million annually.
The SPCA of Central Florida has been designated as one of 3 training centres in the USA where veterinarians will be able to receive training and certification in the use of this new technology.
I don’t know how rigorous Colombia is in respect of their management of veterinary medicine but if they are any good then it is conceivable that chemical castration might be extended to domestic, feral and stray cats in the United States of America and European countries in the future.
My thanks to Dee for telling me about this story.
