They want to approach from above the call, that is a very important detail when choosing a spot to set up and call, if you are trying to get the vantage and calling, you are not going to kill them, and if you do call one in, it’s going to feel like it was sneaking up on you, but that’s not the case, they aren’t like coyotes, they will go out of their way to get above the call.
That’s the hardest part of picking a good setup, is setting up below where you want the cat to come, and still being able to see
You need to use terrain features to your advantage, draws are a good start, it’s a way to funnel a cat into a smaller area. A flat is a possibility too, I killed one I called onto a flat once, it was the only place I could get any visibility
