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.

ScruffGuards are available in disposable and reusable variants. Disposable ScruffGuards are currently only available in Size 9, which is suited for adult mice (20-38g). Sizes 6 to 10 are available as part of the Reusable Range. See the Size Guide table below.

Lower ScruffGuard onto the mouse. Apply a light amount of pressure and you will find that the fur of the mouse will protrude through the middle slot of the ScruffGuard. The sponge ensures that the mouse remains unharmed.
