Tiny rodents perform CPR-like rescue behaviors.

Scientists studying social behavior in laboratory mice stumbled upon an extraordinary discovery that challenges everything we thought we knew about animal empathy and intelligence. Researchers observed mice exhibiting what can only be described as first aid behaviors when their cage mates became unconscious or unresponsive. The mice didn’t just ignore their fallen friends—they actively worked to revive them through a series of increasingly intense interventions, from gentle sniffing and grooming to more aggressive mouth-to-mouth contact and tongue pulling that actually helped unconscious mice recover faster from anesthesia.
