New York Times publishes on non-surgical sterilization
December 2, 2013 - The New York Times Health/Science Well Pets blog recently published an insightful piece, "New Strides in Spaying and Neutering." The focus is Zeuterin, but other non-surgical fertility control options in development are discussed as well.


ACC&D welcomes three new Board members

Dr. Marty Becker endorses Zeuterin

March 11, 2013 - Dr. Marty Becker, often referred to as “America’s Veterinarian,” has been trained to use the non-surgical sterilant Zeuterin.  In this VetSTREET article, he reports on his experience with the technology and its great potential for canine population control in both the U.S. and abroad. 

Scientific research increasingly fueled by prize money
LA Times - Michelson Prize Grant January 10, 2013 - Dr. Gary Michelson is the sponsor of the Michelson Prize Grant in Reproductive Biology, which offers $25 million for the first researcher to create an easy, affordable means of sterilizing animals. Prize sponsors believe that offering incentives gets new people thinking about old problems.

ASPCA® Grant Funds ACC&D Feral/Free-roaming Cat Population Model
ACC&D is expanding a project to better understand and plan dog and cat population control programs, thanks to a $45,000 grant from the ASPCA. The project will engage experts to develop a computer simulation model of feral and free-roaming cat populations based on available data on dynamics of these populations. Once complete, the model will allow those planning and conducting population control programs to use the software to look at their program and better understand how many cats they need to sterilize, how often interventions need to be conducted, what portions of the population would be best for targeting (for instance, juvenile queens versus mature queens), and what changes in the population they can expect over time...
