With a ScruffGuard, you can handle and dose small animals gently, whilst avoiding bites and needlestick injuries. A ScruffGuard can be used to administer substances by subcutaneous, intraperitoneal and intramuscular routes. It can be used to implant microchips subcutaneously for identification purposes. A ScruffGuard is particularly helpful for trainees who are learning to handle small animals for the first time.
