Rats look out for each other
When someone is called a rat, it’s not a compliment; they’re usually being accused of lies or betrayal. Rats are often associated with dirt, disease and a life of sneaking around, but they’ve got a surprisingly big kind streak. Scientists have shown that they will try to free another rat if it’s trapped, and another experiment demonstrated their unselfish nature.
Pairs of rats were placed in compartments next to each other and one was given a choice – pull a lever and receive food, or pull another and gain food for both themselves and their neighbour. Almost every rat pulled the second lever.
