The CatFence system comprises of a hidden wire around the perimeter of the safe area for your cats. This is connected to an electronic control box.
The control box sends a coded FM signal via the boundary wire which is picked up by your cat’s computer collar. When the cat approaches the boundary wire, the collar emits a beep, reminding the cat that they are coming close to the boundary.
If they continue to approach the boundary, the collar delivers a light and harmless impulse which prevents the cat from getting any closer to the boundary.
Cats are intelligent creatures and they quickly learn to understand the beep and will turn back into the safe area.
