See if you can identify the hair in the scat,that might give you a clue.If its muskrat hair( which is fairly easy to identify from squirrel or mouse)It would most likely be mink.

Doesn't look like chicken...

And I am reasonably certain it isn’t cow either.

Fox per chance?

Without putting in under a "scope" to see the tiny particles here is what I used when I lived in MN...... 1. Where did you find it? Close to water is pretty much a give away if it was cold enough to form a layer of ice on the water. Weasels will hang close to the cattails but not venture to get their feet wet. A mink will follow the groceries on land or water and keep going. The weasels were out about every night and were more centrally located around a denning site. 2. Check the (any) bone fragments in the scat, as mink will have some (weasel little or none) and a partial fish scale or crayfish exoskeleton once in awhile is a dead giveaway. Also any partial (tiny) feather quills as mink will catch a bird now and then whereas its tough for a weasel to get one in the wild-- use a toothpick to separate the scat. Both predators feed on the mice/voles/rabbits etc. so hair is inconclusive evidence from my view. and 3. Size for me was easy with the ST weasels there (smaller) and the edge of the fresh mink scat was always smooth like a cigar edge. My view. P.S. I once caught a 4 mink on a 300 lb. stinking/rotting hog carcass with 110 size bodygrips in the snow, that was 200 yards from any water and it was frozen solid. So Go Figure the fresh bait theory on that one?????????????????

Doesn't taste like it either!

Makes some sets and find out for sure.

No expert Joe but judging by the scale of things,that looks pretty big to come out of even a long tail.I'm real interested to see what you come up with.
