This kit is effective fencing (for cats), for use on or against a wooden fence. The set contains all important components for an electric pasture fence of 50 m (extendable to 500 m). Ideal for keeping your pets in the garden. The fence set is easy to install and very effective in use. It works as a +- system, an impulse is only given as soon as the cat touches two wires at the same time. Therefore, two wires must be touched at the same time to feel the impulse. This system does not require a separate ground rod!
