"So, the free rat wants the trapped rat to be free." The free rat tries everything to get its friend out. Mason says the trap has little air holes in it. "And if the trapped rat has a tail poking out the free rat will actually grab that tail and, kind of, pull on it." Eventually the free rat will accidentally trigger a door that opens, releasing its buddy. The researchers repeated this experiment many times. The animals quickly learned to open the door on purpose. But they only did so for a pal, not when the trap was empty or contained a toy rat. And they did this even when opening the door released their pal into a separate cage. So it wasn't just that the free rat wanted a playmate. They seemed to just want to help. The results are reported in the journal Science.
