Cagebreak! Rats Will Work to Free a Trapped Pal, University of Chicago Study

Published: Dec 09, 2011

Calling someone a "rat" is no compliment, but a new study shows that rats actually are empathetic and will altruistically lend a helping paw to a cage mate who is stuck in a trap. Not only will rats frantically work to free their trapped cage mate; they will do so even when there's a tempting little pile of chocolate chips nearby, the study reveals. Instead of leaving their pal in the trap and selfishly gobbling the candy all by themselves, rats will free their cage mate and share the chocolate.
