Buzzards and coyotes get most of ours. We clean a small one once and a while.
I thought that for a long time until we put a trail cam at my deer camp carcass pile.
It was a bunch of hogs that ate those hog carcasses...
Ate them down to the skeletons and in short order. It's amazing what 20-30 hogs can do to a pile of dead hogs...
I'll eat a young one, but after seeing that, most of my pork comes from the grocery store.
Old timers would catch a possum, bring him home, feed him for 2-3 weeks then eat him. Hogs are about as nasty as possums.
And, wear gloves cleaning them for Lepto, Brucellossis and other interesting diseases they carry.
