We use electric poultry net all around our ranging areas and coops. It is the best deterrent for any creature that stalks, but not as good for the types that just leap over without skulking around the perimeters first. I have seen a stray dog come in contact with it on more than one occasion- but the same dog never does it twice. We lost birds to a bobcat prior to using the fence, but never after it was installed. A feral cat being fed by a close neighbor took two birds whist that neighbor was away on a cruise. It just cleared the net in a leap; I was able to see it do that one time, so we trapped and removed the cat. After that, we put in a taller net on that vulnerable side of the yard and had no further problems although the neighbor still attracts feral cats and then leaves on long cruises. Our nets come from Premier 1 on line. The selection is really varied. We have been using this for three years plus for our birds who free range about a half acre all day long. It also keeps out steers out of the poultry area...they could just barrel through, but always touch it with a damp nose first, thus they learn to respect it.
