I know just how you feel, I love cats and dogs, we are quite lucky in our close as far as dogs are concerned we do have a lot of people come through to walk their dogs but I would say 99% clear up after them, and I am always on hand to offer them a bag if they don't.

How I wish I could say the same about the cats we are surrounded by them and most of them have 2 cats per household and they love to use our lawn as a toilet, we do shoo them if we catch them on the lawn getting comfortable to perform but turn your back and they are back again almost in defiance.

Have never found any deterrents that works and we have tried lots from powders, cat scarers, battery operated do dahs but nothing works.

If any one has a full proof method you could make a million.
