Is the procedure painful for the mouse?
Tattooing is generally regarded as a safe identification procedure that causes minimal pain and distress to the animal. In most instances, pain and/or severe bleeding are the result of poor tattooing technique. Because the SOMARK Labstamp is an automated tattooing machine with built-in safeguard features, the likelihood of pain or distress due to human error such as tattooing too deep is reduced substantially.
