They are walking, the cat and the girl and Red. Red hates, hates, hates the cat. It dresses up in human clothes and speaks smart and acts like a person when really it is not. She likes it when the cat is scared of her.
She knows the cat will never be strong enough to eat her up. She knows this, but when she first saw the cat a thrill of fear ran down her back and Red was afraid. So she covered it, she acted the crazy woman, she hid in her created persona.
It would have been genius if she didn't worry sometimes she is getting lost in the Red that the princess and the cat knew. It would have been the perfect way to hide, if she wasn't worried that she would not be able to find her way out of her hiding spot someday.
On the nights when Red believes in God and curses him, she rolls over in bed and cries, and prays that she can stay herself.
