Mice! They were so prevalent here when this place was 1st hacked out of the woods that we lost a lot of sleep and I live trapped them by the sheeer hundreds, to take far away & release: then 3 summers ago, thrifty adult mice were observed staggering around in bright sunshine ( not a mouse's favorite thing, dontcha know ) and dying of a seemingly neurologic condition. This summer, for the 1st time ever, no mice stormed the camp, trying to break in. I got to sleep every night during the usual mouse wars week.... no mice. No mice at all. I couldn't interest any biologists in my observations... so I just watched & worried about the foxes, coyotes, owls and all else that depend on mousie parts for their existence: the food chain was broken & it frightened me some. But then in October, I saw a few young ones.. today, I'm seeing hordes of them again and there's mouse doo in my storage boxes that are kept on the enclosed back porch... mouse doo, mouse piss, mouse nests in everything and everywhere!!! Yesssssss! Things are back to normal and the rest of my woodland critter neighbors will fare well this winter.
