July 1, 2013, Pentax Q + 06 lens. I was sitting on the deck of our vacation rental cottage, eating roasted peanuts and tossing the shells in the yard, when I heard the soft scrabbling of claws. I glanced up to see a squirrel peeking up over the edge of the deck at the corner of the cottage. I watched in amusement as it cautiously crept down the deck, up on the railings, and over to a picnic table a few feet away, where it sat eying me hopefully. I tossed it a peanut, which it greedily grabbed and carried to the nearest tree branch. Little did I realize that I had just triggered The Great Squirrel Invasion of 2013. Within seconds, squirrels began converging on the cottage from all directions - down from the surrounding trees, out of the woods, and from nearby cottages. I also learned that day that squirrels growl and hiss at each other just like cats.
