There is cat crap all over my lawn - has anyone got any ideas about how to deter the little buggers! . Now I hate cats and I don't want dd playing outside. Am mad as hell! I think it is primarily next door's beautiful but stupid fluffy thing! It obviously feels that our garden is its patch as it was already ensconced when we moved in, but now it's pooing and being sick all over our lawn!! Yuck, yuch, yuck!! We have one of those sensor things which emits a high pitched noise when cat goes through the beam, but either it doesn't work or the cat is deaf. Does zoo poo work?
