Cats dump on my front lawn all the time and I have to go and clear up after them. Disgusting. GET A LITTER TRAY AND KEEP THEM IN - half of the day at least. in new Zealand they have a curfew and no cat is allowed out at night. Irresponsible pet owners make my blood boil - dog owners who don't clean up their dogs yuck- vile individuals. I hear Jack russels don't like cats and will rid your garden of them, permanently......
