A previous post that is being repeated…
I find this thoroughly fascinating~
1) That squirrels and other animals even know how to make nests,
2)That they have learned to use available materials to ‘feather’ the insides of 
their nest to keep it warmer and,
their nest to keep it warmer and,3) That they have even learned to use exfoliated bark of a tree, not even known to still be in existence since prehistoric times until 1947 (Dawn Redwood), as a great insulator in their nests~
Check out this picture of the bark of a nearby tree in my backyard. If you look closely, you will see the squirrel.
Tell me God doesn’t have a plan for all his creatures!
