Good Morning , can anyone help with a problem which I have had for several years now. I have s reasonable lawn but every year in April I have a visitor which urinates on the lawn causing the mess which you can see. It must be something which hibernates because it just starts at this time of the year and disappears after s few months. It's not a dog, we don't have one or our neighbours. If it were a domestic animal it would occur throughout the year. Same with a fox. Does anyone think it could be hedgehogs . It's so annoying. Any help would be appreciated.
