I wonder if, pipe, cigar, similar odors, are unnatural odors in the sense that historically those odors are not present when a predator is lurking, so they are not, of themselves, bad or even startling, but maybe mildly attractive in the sense of curiosity for what is making them.
On the order of a person just walking " looking for the lost wallet" as G. Fred puts it does not normally look like a predator, but a person moving slowly and intently, maybe slightly crouching, represents a predator at work.
Hmmm the new skunk scent, carbon clothing and ozone generator wrapped into one..... Arango Sportsman 400 cigars ! I would use them, no matter how "cheating" that appears!
