How do you use the Mouse Pipe 2?
You should not blow into it as hard as if you were whistling to a dog at 100 metres.
A mouse does not whistle, it chirps quietly and excitedly. Place the mouse whistle
under your upper lip and breathe the excited sounds of the mouse into it in quick succession.
The fox hears these sounds at over 400 metres. If a fox comes into view
after the squawking, only work with the mouse whistle.
