I use it all the time, ecspecially to bring them in that last little bit, regardless if it is down, up, or across a hill. I have not had the hang up on a hilltop necessarily except for if it a really steep hill or they hang up on the ridge just before the one I am on, and strur back and forth. The purr alone has sealed the deal for me more times than anything else as it seems to put them over the edge to come in for a look. The leave scratching just adds a little more realism to the set up, cause that is what content hens are usually doing in the woods.
