"Bartal et al showed that rats can demonstrate empathy by having a free rat
rescue his or her cagemate, which is placed in a plastic restrainer. Once the
rats learned to open the restrainer, they only opened it if there was a
cagemate in it, i.e., if it was empty or had an object inside they left it
locked. Also, when presented with a locked cagemate and a locked piece of
chocolate, the free rat would unlock both and share the chocolate. That's
better than many politicians."
This is a great study. Very cool. We used to have pet rats, but it's hard to
deal with losing them after such a short life.
