Summary
This drawing represents a playful cat who is messing around on a young girls head. She is reluctant on telling him to stop so she puts her head into her hands and bares the humiliation of how the cat is mucking about. 

I think the cat represents being young and playful. I think this because of the position he is in and the huge grin spread across his face.
Although the girl on the other hand is fed up I think this represents growing because as we all know in the story of Alice and wonderland it is all about growing up, and Alice not playing back with the Cheshire Cat shows she has matured and is to old for messing around.
