OK. Just wondered. And on a lawn the lion poo would not work well. I know that Jeyes Fluid - applied in solution - worked at stopping a dog which was instructed by its owner to use the lawn at the flats. The smell is so strong that all the clues they use to trigger the bowels disappear.

(The dog owner sent her son out to get the dog to "go" in front of the windows of the neighbour she did not like, and kept signalling to the boy to get the dog to do its "business". Both the boy and the dog were very put out. It was very funny to watch - but not what I had in mind when I treated the lawn, which I did to disinfect it.)
