Forget the lip thing boys! Open that mouth[remember the fish kiss thing from child hood, form your lips in O shape]and flutter your tongue with no call in your mouth. When you can flutter the tongue enough to feel it bouncing on the roof of your mouth then put the call in your mouth and do the same thing. It is going to tickle your tongue something terrible until you learn to control it. But once you do, you will be able to raise and lower volume and pitch. I can do a fighting purrs this way. I can match your slate purr. It did take time to learn, but it is well worth it.
