Mice Can Feel Each Other's Pain, Says Scientists

What hurts a single mouse can hurt every mouse in the immediate vicinity. That's the conclusion of a latest study that examined the social transfer of pain in mice, carried out by scientists at Oregon Health & Sciences University in Portland. The experiment, published on Science Advances, show that pain can move from one animal to the other without any illness or injury required. When a particular group of mice was given a painful stimulus, another group that was completely unaffected exhibited the same kind of increased sensitivity at first.
