I do not think so. My dog was always right by me, and any cadburies were picked up unless well off a road or trail and in tall grass. Cats come to people's yards and bury their cadbury's and piss in your flower beds and children's sand box. While burying their business in flower gardens they dig up flowers. The piss smell if in a bed by a basement window can stink things up enough to be smelled in the basement.
