Freedom Fence
Cat owners looking to keep their cats in their own garden might want to take a look at something called Freedom Fence.
Freedom Fence™ is a cat deterrent system for keeping pets within the boundary of a property using a low frequency radio signal. If a pet equipped with one of the receivers approaches the boundary the collar will beep to warn the animal to move away. If it does not, then it will receive a small ‘correction’ similar to a static electric shock you get from touching a car door in summer. The correction doesn’t harm the animal but is uncomfortable enough that it doesn’t want to repeat the experience, and the pets soon learn, within a week or so, which areas are no-go. If you know of anyone who are trying hard to keep their pets from wandering too far away from home it might be worth mentioning to them.
Their website is http://www.freedom-fence.co.uk and the system apparently works on dogs too.
