About Mouse & Rat Ear Punches
Ear punching is commonly used for identification of mice and rats and involves using a special punch to either produce a small (0.5 to 2 mm) notch near the edge or to punch a hole in the middle of the ear. The cutting edge of the rodent ear punch should be disinfected or the entire punch should be autoclaved after each use.
