We have had exactly the same puzzle here in Dorset. Black droppings, soft and irregularly shaped compared to mice and bats. The dropping were wet and green if squashed when found on the leaf.... and dry and soft or even powdery when dry. They were completely odourless. When I saw them I immediately thought caterpillars. They only occurred at night. Search as we did we found no caterpilllars. I believe they are caterpillars and am very interested to see a picture or a description to find out what they are.
