Rats look out for each other

World of Animals - - Animal Kindness -

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.

right Sci­en­tists be­lieve that the em­pa­thy dis­played by the rats in the ex­per­i­ment is in fact com­mon across mam­mals
