Cat scarer extrordinaire

After suffering many years of cat crap on my once immaculate lawn and having tried many ways to repel the blighters,  I have discovered by chance a method which has succeeded remarkably.  Running 24/7 it produces an electric spark which generates an extremely broad band noise spectrum as well as electromagnetic radiation.  The gizmo is powered by 12V  battery.  NMC (NoMoreCrap) has been seen since.  Although I don't like cats at all I was careful that the gizmo should cause no harm to the little darlings.  Ultrasonic deterrents apparently work for a time until the cats get used to it,  then useless.  Bottles of water do not work. 

The gizmo was designed and engineered by myself at little cost of  course.  Not really a commercial product this far.

    Maybe you should try Dragons Den.

    TEST IT ON A YOUNG CHILD. THEIR RANGE OF HEARING IS MUCH BROADER THAN ADULTS' AND THEY MAY BE AS DETERRED AS CATS BY THE SOUND.

    How is wildlife in the garden affected by this (ie birds etc. ?

    Can you invent something to get rid of neighbours ??
