Been looking at these, reviews say they don't work... However not for mice.... For the local cat that keeps shitting in my front garden 2-3 times a week
I know exactly which cat it is, we had new neighbours few doors down just before Christmas, just after the cat poo started. Funnily enough, they have a cat.
I thought about saying something to them. But what can they do? .... If I catch it I know what I will do, because I never use my front gate, I always hop over the wall. Only once into freshly laid poo! Next time the cat gets it
