I was cleaning off our deck when a baby squirrel feel from an 8 ft tall light on our deck. His nest apparently is in the top of the light. He let out a squeal whenever he landed. His body not including tail is about 4-5 inches. He did not move, but shivered a bit when we approached him. My husband picked him up and he gripped with his feet, but did not run away or attempt to get away. We put him inside an old hat to keep him warm and placed him on the ground near his nest.
What else can we do?
