In The Sword in the Stone, how does Kay handle his predicament of being held in a hutch by Madame Mim?

From the text:

Poor Kay was weeping in the corner of the end hutch, lying on his face and paying no attention to anything. Before Madame Mim had finally thrown him in, she had pinched him all over to see if he was fat. She had also slapped him, to see, as the butchers put it, if he was hollow. On top of this, he did not in the least want to be eaten for Sunday dinner and he was miserably furious with the Wart for leading him into such a terrible doom on account of a mere arrow. He had forgotten that it was he who had insisted on entering the fatal cottage.
