My favourite childhood book was Mog the Forgetful Cat. I have always loved Cats, and owned a Mog stuffed toy too!
Mog is a forgetful Cat who lives with the Thomas family. They see Mog as a nuisance, as the poor cat keeps forgetting things, expect the daughter Debbie, who is always on Mog’s side. Near the end of the book, Mog does something brave that ultimately saves the Thomas family and they begin to realise that they need Mog in their lives.
Lots of repetition and beautiful illustrations… Makes me want to read it again now!
