DW: I guess this is where we get steel wool?
An Austrian inventor has spent three years building a kind of chain mail for sheep, hoping to protect them from wolves. Rudolf Schaubach, from the city of Fillach in southern Austria, was inspired by the rising number of wolf attacks in his country and neighboring Germany. His creation is a light plastic net covered in sharp spikes, meant to hurt a wolf enough to make it think twice about biting. As he put it, a wolf is smart and would not try to bite a second time.
But the reception from farmers has been mostly cold. One farmer with about 1,000 sheep called the idea impractical and harmful, warning the wool could get tangled in the mesh and that wolves would just switch to biting the legs or head. Others said no one could afford to outfit thousands of animals. Schaubach insists critics are judging from photos, and he has now stopped testing in Austria and is looking elsewhere.
