One of my neighbours, three doors away, has approximately 6 to 7 cats (it's hard to say exactly how many) and the cats have been using my back garden as the place of choice to leave their litter. I would say this has been going on for some months now, but I have only noticed this recently because I have started cutting the grass after the winter months. My garden is full of litter and i can't even walk out to my clothes line without stepping in litter. The smell from this is horrendous. Also, I recently noticed more litter along the footpath at the side of my house. I have cleaned up the litter as best I could thinking this might deter them from coming back but to no avail. Not to mind the inconvenience of this, I am aware that cat litter is extremely dangerous especially where there are children playing. Please help!
