Upside Down Squirrel

Upside Down Squirrel
The other day I looked out the kitchen window and saw this squirrel meticulously checking all of the spaces in a pile of concrete panels. He did this mostly while hanging upside down. Later I checked the cracks and noticed moss growing there. I assume he was eating the moss. Those concrete panels are all that is left of the house we demolished to make way for the new house.
