Ominous omen

Today, I saw two dead squirrels in Mount Greenwood and two more dead ones in Beverly. I find this unusual because I rarely see any dead squirrels. What happened to them? Three looked like they were killed in traffic, but one was on the sidewalk at the bottom of a tree. Is there some kind of epidemic? As I was driving home this afternoon, I saw a squirrel in the middle of the street eating an acorn. I would have run it over if I had not swerved to avoid it. It didn’t even budge!

Please help me!
