I didn't downvote you, but my guess is that your comment is basically wrong. Even a "small" inconsistency would behave in a similar way assuming it had physical interactions with the outside world. For example, the living cat would breathe in air and metabolise carbohydrates, while the dead one would be eaten by bacteria. The living cat will also cause humans who see it to pet it, while the dead one will cause them to recoil in disgust, which should split the world or something. I make no remark on the accuracy of the original comment, since I find it a little confusing, not having read the story/paper yet.
