My husband was fed up with picking up piles of cat poo before he could mow the lawn. Now the (many) neighbourhood cats go elsewhere! (apart from one, preumably deaf). Young children CAN hear the noise and I would get quite cross with a neighbour who refused to deal with this problem. We turn the alarms off whenever children are outside - they are scary enough to keep the cats away by themselves! This also saves the batteries. You need to be careful with other pets as well. The hamster didn't like us testing the alarm inside and things like rabbits kept outside may be affected. For us, it was well worth the money.
