Zeuterin is a compound of Zinc Gluconate and Arginine.  These are both naturally occurring compounds in the body of humans and animals.  In a precise measured amount, Zeuterin is administered under light sedation using a small gauge needle directly into each testicle.  The sedation is reversed and the pet is awake and ready to return home in less than 20 minutes.  Zeuterin is safe, effective, pain-free and costs less than traditional surgical castration.  Click here for more information.
