Royal Mail threatened to stop delivering to a couple over claims their naughty cat was attacking posties through the letterbox.
A letter sent to Lee Haynes and Jo Woodley said their tabby's roaming paws were making visits to their house dangerous.
The pair say Ernie, a "placid" three-year-old, was just playing - but Royal Mail asked for action to protect its workers.
So Lee and Jo from Tamworth, Staffs., have now installed an exterior letterbox their pet can't get at.
