The festive fourth book in this fantastically successful new series for 4-6-year-old readers about Ava and her imaginary cat, in hilarious rhyming text with adorable illustrations. Told in full colour throughout, this is the perfect stepping stone from picture books to older fiction.

Pip Jones lives in East London with her partner, her two daughters and a real invisible cat (it doesn't catch mice, but it doesn't need a litter tray either, so there are pros and cons). She writes a lot. She even owns a writing cloak! And she spends days on end working out how to get good rhymes, such as 'snuffle' and 'kerfuffle', into stories. Pip won the inaugural Greenhouse Funny Prize in 2012 with Squishy McFluff, The Invisible Cat, her first book. Ella Okstad returned to her native Norway after graduating from the Kent Institute of Art and Design in 2000 where she now illustrates children's books for both Norwegian and British publishers. Squishy is her first imaginary cat.
