Squishy McFluff the invisible cat meets mad nana dot

"Ava and Squishy are up to their normal no-good when Dad whisks them off to Nana Dot's--Mum's got to go to the hospital to bring back Ava a baby sister! But Mad Nana Dot's lost her glasses so can't SEE Squishy McFluff . . . and a trip to the hairdresser's, the post office, and the fishmonger all end in adorable disaster"--OCLC.
