rattling works through all three rut phases as well as grunting..but there are different grunts and growls you can make that sends a different message..and combining them almost always ends up with success if you do it at the right times and make the right sounds..using the right scents etc..i know it sounds a little confusing but the best way to learn is practice and through trial and error..the best thing to do is to purchase a dvd and watch it..read magazines and take notes
