June 2023 News from the Alliance for Contraception in Cats and Dogs: 

 "At ACC&D we’ve talked about the dream of a “spay shot,” and it’s now one step closer to reality with research on a single-injection treatment for female cats."

 "The past two years have, if anything, deepened our enthusiasm about a technology being researched with funding support from the Michelson Found Animals Foundation/Michelson Prize and Grants (MFAF/MPG) program Link. Teams led by Dr. David Pepin (Assistant Molecular Biologist, Massachusetts General Hospital) and Dr. Lindsey Vansandt (Veterinary Theriogenologist, Cincinnati Zoo Center for Conservation and Research of Endangered Wildlife) conducted a very promising series of studies. These have yielded NO PREGNANCIES in treated female adult cats in two years of breeding trials, with continued positive results through year 3 based on hormone levels. Studies in dogs have begun in 2022. The work for cats has transitioned from research into a product development plan, working with the U.S. Food & Drug Administration (FDA) on a path toward regulatory approval. ACC&D is helping MPG identify how shelter-adopted cats might get early access to this technology while helping with a field trial... And funding for new approaches continues...   As exciting as research is, though, (unfortunately)  technologies described above won’t be commercially available for some years."   Stay posted.    Hopefully this treatment may one day be offered without a shot.   Thank you.
