Having a chemical solution to replace female spayings would be a total revolution and have a bigger impact; but still, an injectable sterilant for males would be of much help and reduce our costs significantly. We do an average of 2,000 spay/neuterings per year, 35% males. Considering that last year we spent 60,000 euros on anesthetics and medicines (mostly antibiotics), we could save approximately 10,000 euros [approx. $13,000] per year and increase the number of castrations thanks to a quicker procedure.
