The first thing that came to mind after that was the phrase "yesterday's news," which got me thinking about what if there was a little girl named Yesterday who put out her own newspaper and called it "Yesterday's News?" And she has a cat named Headline or Byline who "helps her," and by that I mean mostly rolls around in her notes but also sometimes discovers things or gets her out of jams too. And maybe they solve "mysteries" and uncover "secrets" around the neighborhood or whatever. Kind of like Harriet the Spy meets Nancy Drew, except with a super horrible name.
PSA: Do not name your child Yesterday. Do not name your child Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday (even if she's a vampire), Today, or Tomorrow, either. These are not names. Also a better, if less thematically appropriate, name for this cat would be Waffles. End PSA.
ANYWAY. There you go. I should just really stick to drawing.
