Adopters want to know male cats won’t spray and male dogs won’t have the fighting, roaming, humping tendencies. If male chemical sterilization was available that was permanent and reduced testosterone thus reducing undesirable behaviors, we could alter more females with the surgical time saved and hope that soon a chemical sterilant will become available for females. In our application the new product would be game changing. A simple injection that did both [sterilizes and modifies behavior] would be a good answer and well worth the dollars spent for regulatory approval. An even better answer would be a chemical sterilant for males and females but reducing our surgical time by 50% for the male population would be huge.
