2. Sniffing and Grooming: The First Signs of Concern
When a mouse discovers a cage mate lying motionless, its first reaction is typically a round of intense sniffing and gentle grooming. These initial acts are more than routine social exchanges—they indicate a rapid assessment of the unconscious peer’s condition.
Scientists interpret this behavior as a sign that mice quickly recognize something is amiss, prompting them to investigate further.
Such early responses underscore the possibility that mice are wired to detect and respond to signs of distress in others, as highlighted in this Nature News report.
