Nothing, unless someone disagrees; once someone argues that the cat isn't furry, stop using 'is' and it will be clearer what you really disagree about. Consider a more realistic example, e.g. "Russia is a dictatorship" vs "No it isn't". What are these people arguing about? A fact (they disagree over which things Russia has done), an opinion (they agree on what Russia has done but disagree on whether those things were bad), semantics (they agree on what Russia did and how bad it was, but disagree on whether that meets the criteria of a dictatorship), or something else? Using e-prime isn't a panacea against this sort of confusion, but it is almost always helpful.
