Rats Have Empathy 

Thursday, January 26th, 2012

A rather fascinating, if somewhat cruel, experiment has indicated that rats are capable of feeling empathy.

Empty cages didn’t inspire rats to learn how to open the door nearly as well as those who were motivated to rescue a trapped rat. By the end of the experiment, only five of 40 rats learned to open an empty cage, while 23 of 30 rats learned to open the cage to free an occupant. (And trapped stuffed animals fared no better than empty cages.)
