In general bobkitties are usually slow to come in, or come in and lay up out of sight for a time before coming on in or leaving out the back door. A kitty stand can run up to a solid 45 minutes or more out here, but as little as a few minutes sometimes in very tight cover. While young jack or cottontail calls do work, they tend to bring in coyote/fox much faster that bust the stand. Higher pitched as in bird in distress calls often work much better, at lower volume or lip squeeks when seen close. And many folks over call when just enough to get/keep their interest is more than enough. A simple feather on a string hanging on a bush is an effective decoy for them to hold their interest, keep their focus off you as the source of the sound, maybe spark them to come closer. I made all my own mouth calls for over 5 decades, and made specific ones just for bobcats and cougar, both enclosed and open reed. Here in the west getting a bobkitty in before other predators is the trick, getting a cougar in and actually seen can be a very long stand. IMO all predator calling is better done as I always did it, alone. At night you can get away with more. But then most of my predator hunting was ADC for landowners where they were often shot at or disturbed by hands, so were more cautious. On some properties so much so that a 300 yard shot was a short one for coyotes and cats.
