It's Wisconsin-it's 0 degrees-I really don't think it's "shedding". We are noticing lately that now every squirrel in the neighborhood is losing his or her tail fur. The tails aren't bare-just very very thin fur. I know that normally they wrap their tails around their bodies to help keep warm. This has got to be either a mite or mange problem. But wouldn't you think the parasite would freeze in consistenly 0 degree weather? Can anyone shed some insight on this for me? No, it's not a predator as all of the squirrels are consistently the same. They do seem to scratch a lot also........the rest of their bodies look ok-but hey, it's Winter - we have 74 inches of snow and frankly, I just can't see their bodies that well. Whiteiris in WI
