I personally have seen a partially eaten young doe in a tree. It was not tied up or anything of the sort, just kinda up in the tree and jammed in at a position that it would not fall. How would that be rationalized then if the cats are not known to be tree eaters? Perhaps somebody creating a scene trying to fool other people? The situation I got into was disturbing and still somewhat haunts me when I get that feeling of being watched or stalked. Simply trying to rationalize... a hard hit roadkill deer that has been partially eaten by coyotes or some other predator/scavenger might have the appearance of a cat kill. A person who finds that could put it up in a tree to further lend credibility to the story, this making themself relevant in local news. It’s a stretch but seems plausible for a lonely backwoods person with a good dose of prankster in their blood. That would explain a few scenarios, but not the extent of which has been reported. People are just lying about a chunk of them is also a good possibility I suppose. Are there any North American animals known to eat in trees that would be strong enough to lift a yearling whitetail?
