I love observing the fox squirrels in my backyard. I always wondered why some of the mother squirrels suddenly increased the size of their litters with more kits during the summer. Recently I saw seven kits with a mother squirrel who used to have two kits. I researched why this happens and it turns out that mother squirrels adopt orphaned kits from their colonies. Squirrels are remarkable and caring creatures. If you can, observe the squirrels that live near you everyday and see what they do.
