So rainshadow, school me on whistlin. If im on tracks, and stop to do a little whistling, should i expect a vocal response if a cat is coming in? Not sure what im doing there, just experimenting with it. Like today following a lukewarm track, the cat went through a big draw that is a lion highway. Tons of activity there. So i stopped and sat at a good spot down low in the draw and was doing a little whistling, like maybe 5 times in 20 minutes. The sound was echoing real well, reaching out. If im not getting any vocal response does that generally mean nothings going to happen, or will they commonly come in to check me out without vocalizing back at me?
