Can You Not Feel a Mouse Bite? Why Pain May Be Absent
The sensation produced by a rodent’s bite depends largely on the dimensions of the wound. A mouse’s incisors create a puncture typically less than 2 mm in length and only a fraction of a millimeter deep. Such a shallow intrusion often fails to reach the dermal layers where free nerve endings are concentrated, leaving the epidermis—where only a sparse distribution of nociceptors exists—largely unactivated..
