Well, I think I may have won round one.
Upon returning from lunch with my wife I saw the smallish squirell sitting on the edge of the roof as we entered the driveway, luckily he sprinted over the roof rather then ducking back into the attic.
I proceeded to don my camo parka (brown wetland grass patern), grab my gun and find a comfy spot leaning against a big pine tree. I figured I'd wait and see if either the creature returns or another one emerges.
I waited peacefully for an hour and watched countless squirells chasing each other from tree to tree and even had a few come with in 20 feet, but as I could not 100% ID the culprit I let them go; I'm not completely morally bankrupt.
After an hour and my leg going to sleep, I climbed the ladder in hopes that the attic is empty and attached 2 scraps of English Walnut (left over from an old attempt at furniture repair). At least the walnut should be harder then the ceder siding or the plywood.
