My two house cats, Sammy & Rosie, (named for two of the Hobbits from the Lord of the Rings) love to watch backyard activities from the near ground-level kitchen window. One day, Sammy was taking up the whole window as he often does and Rosie was desperately trying to push in to see what was fascinating him. Unbeknownst to Rosie, it was a visiting cat.
Well the visitor apparently said something insulting to Sammy so he yowled back something even worse at the top of his lungs (!@$$*^!!). Rosie thought he was "talking" to her, rose in the air and came down running to hide under the couch.
