If you get a visit from the little tiny cat, it means that your article already appears differently where there is a danger of plagiarism maybe. This could prevent curators and voters from voting for you. If the posts you post are from yourself and you have posted them only where also differently, you must tell the cat. There is, as far as I know, a white list where you can enter your posts. How this works now I can not tell you. What is important on steemit? Write your own articles, little copy and no plagiarism publish.
