Agree with everything you say Dave, but unfortunately as Bill says there is little we can do. I now wear disposable gloves when gardening. I have tried various things over the years without much success, last year I tried a product called "Silent Roar" which is pellets soaked in lion urine and found this helped.

With regards dogs, someone's is roaming about Grosvenor at night as twice during the last 3 weeks I have had to remove dog poo from my back garden.
