A term used to describe black and white cats that have a small black patch under their nose, resembling the patch of hair under that of Adolf Hitler, however they do not have anything in else in common with him. The term "Hissler" is a play on words of "Hitler", with "Hiss" being put in place of the beginning. This is a reference to the hissing sound a cat makes when angry, which coincidentally, Hitler often was. (Or at least he sounded like it since he did a great deal of shouting.)
