What ate that hog was probably other hog’s, they’ll eat anything they can find. My wife shot a sow just over 200 lbs about a month ago, two days later everything was gone except a little hair. A sounder of hogs can consume a cow carcass in short order and are excellent at cleaning up road kill.
Whatever lugged that intact deer head for a mile, and then jumped a 4' fence probably wasn't a hog. My thinking was that hogs would have devoured most of it near where they found it...
Last year. my wife and I did get a clear (<50 yds) look at a BIG cat with a long tail crossing the road about 4 miles away on the same creek drainage. TPWD says the cats aren't here, but folks swear they have seen them within a mile of my place -- and now I believe them!
BTW, we live in the far northeastern Texas Piney Woods. What State are you in?
