Query: Waste of Time and Money

I have had cats pooping in my front garden for awhile, so I was excited when I received my Contech Catstop and put it outside, and for the first two days there was no cat poop! I thought my problems were solved. That was until I came outside on day three to see a huge mound within three feet of the Catstop. After that, the cats would poop right next to it, in front of it, behind it, they had absolutely no respect for it at all. Also, the thing eats up batteries like crazy. Don't bother wasting your time or money. Although the vendor was very receptive, it just is not worth it.
