2. Squirrels Can Adopt  As Well

If you thought only humans can be altruistic and have a big heart, well think again. When a kit’s parent dies or leaves them behind, another squirrel will adopt them. A study from 2010 showed red squirrels will raise another one’s kit  if they are orphaned.

It is unlikely since they are among the asocial animals, however the study showed they will only do so in the case of a relative, and even in that case it’s still uncommon.

The research mentions that in two decades only five cases were found, and that occurred when the mother died and the adoptive parent was also nursing.
