An interesting concept. I have never personally tried baiting for cats. Comparing the method to those used for other species of cats around the world isn’t really valid. What is acceptable in one place wouldn’t be allowed in another place and time; and as much as they are alike, cats do have different habits.
For instance, back in the hay day of tiger hunting in India it was common practice to stake out a live goat or cow as bait; wait for a tiger to kill it, then sit up over the carcass waiting for the cat to return. That just wouldn’t be acceptable here and now.
Baiting cougars with meat has been tried to a limited extent, and has not been proved very productive. In most cases a cougar prefers to make its own kills. It will at times eat meat that it hasn’t killed for itself, but with few exceptions it will not eat tainted meat. Unless the cat is very hungry indeed, as soon as a carcass begins to sour it is done with it.
Leopards, and to some extent African lions, are scavengers. Putting out baits for these cats has been an accepted and productive way of hunting them for years; and I assume it still is. I see that we now have an experienced African Professional Hunter on board (in addition to Lochi). Maybe one of them will see this thread and give us some insight.
Baiting with scent may have possibilities. I remember reading something about this several years ago, and I just got the book it was in from my book shelf. The title is “Hunting Predators For Hides and Profit”, written by a Canadian I believe, Wilf E. Pyle. I remember him stating that he did put out scent (catnip I believe, and possibly glandular or urine scent as well) for bobcats. The idea was to attract the bobcats to an area, and keep them in the near vicinity. He would return and call there frequently. It’s been quite awhile since I read the book, and I don’t recall if he said how effective it was.
