Problem
Current methods of spaying and neutering animals rely on surgical procedures that require anesthesia and post-operative recovery, leading to increased costs, potential complications, and limited accessibility, particularly in livestock and free-roaming animal populations. The overpopulation of unowned animals continues to be a significant issue. Surgical castration of livestock often occurs without adequate pain management.
Solution
Epivara is developing iSpay and iNeuter, single-injection alternatives to surgical spaying and neutering for both companion animals and livestock. These injections aim to provide a safe, quick, and permanent solution to prevent unwanted pregnancies and reduce undesirable behaviors in pets. For livestock, iNeuter-S offers a humane alternative to surgical castration, potentially improving meat quality by reducing hormone levels. The single-injection approach eliminates the need for anesthesia, surgery, and post-operative care, offering a less invasive and more accessible option for population control and animal management.
Target Audience
The primary target audience includes veterinarians, animal shelters, livestock farmers, and organizations involved in animal population control.
