Role in the film
In the film, Dinah is Alice's cat. She is first seen sitting with Alice in a tree and listening to Alice's sister read from a history book. Alice then makes a crown out of flowers and puts them on Dinah's head crowning her the flower girl cat. Then Alice's sister tells Alice to pay attention to her history lesson but Alice refuses to because the book has no pictures in it and tells her sister that in her world there would be books with nothing but pictures in it to which her sister replies to her nonsense. When Alice hears this she picks up Dinah and tells her that in her world everything would be nonsense because everything would be what it isn't such as Animals Would Talk and live in Houses because Alice's World would be a Wonderland. Then Dinah and Alice spot a White Rabbit with a coat on and a pocket watch and they chase after him wondering where he's going. Then Alice falls down the Rabbit Hole and Alice waves goodbye to Dinah as she follows down the rabbit hole. Dinah isn't seen after this but is mentioned by Alice at the Tea Party with The Mad Hatter, The March Hare, and The Dormouse which frightens him when he hears that Dinah is a cat. Dinah is finally seen at the end when Alice awakens from her dream and Alice picks her up and takes her home for tea along with Alice's sister.
Dinah appears as a Vinylmation in the Alice in Wonderland series and next to Alice in a collectible figurine.
- A test cel setup of Alice, Dinah, and the Sister from the final scene of the film shows that Dinah was a black cat, not orange. Also, in a Big Golden Book by Al Dempster, the colored image of Dinah shows her as a black cat. Early designs for Dinah were lifted directly from a Figaro model sheet.
- Dinah makes a cameo appearance in the the new Alice: Through the Looking Glass movie, but she is neither red nor black; she's a tabby cat, so she's brown and gray.
