I know a lot of posters have problems with cats, but I think mine is a fox. I am finding mess almost daily at the moment. This is quite a new occurance and happens in weird places like on an upturned plastic plant pot, pieces of crock, and bricks. They seem to be getting braver as I am finding it nearer the house on the patio. I do not believe it to be a cat as I think it is too big! Is there anything to deter them or is it going to be just like the cat issue - NEVER ending?
