Mighty Man against the might mouse -

not wishing to appear cruel, however, we do have a little visitor who needs to be captured and removed - so a bit of ingenuity was called for to devise a cunning trap !!!!    So, the little chap has to appear, smells the chocolate and cheese and sets off up the plank, reaches the top, sees an even bigger bit of cheese, jumps into the pot  (which is about 12 inches deep)  and cannot get out - easy.
