Interesting videos, Irving. In the first one I wonder if they didn't actually use a predator call to bring the bobcat in. But I've had close curious encounters with a bobcat, a few foxes, a coyote and several pine martens. I've also closely approached numerous deer and a few elk by mimicking grazing, even touched and petted a few, but I'd be very reluctant to do that with a mature antlered buck or bull.
