Shep has been standing on this chair to reach the Christmas ornaments and un-decorate the tree. Neko decided to leave a little message for him to let him know that standing on the chair is not allowed. (That “now” should be read as “no”.)
Un-decorating the tree, however, is apparently kosher in her books, as there are no longer ornaments on the bottom half of our tree but her room is looking quite festive.
