I've been looking out at this back yard for 59 years, never before saw this creature which --as we speak -- is snuffling along a downed limb of the willow tree right in front of my office window (what little I can see out through the wreckage at the moment.) I'm sure it's not a dog or a cat. Long hairless tail. Considering how small and fluffy it is, it's surprisingly un-appealing. Looks sort of like a ghost. I have the impression the name begins with "o"?
