t is as if normally there is a lubricant ... not in the body ... a spiritual lubricant ... it's hard to describe ... and without it, life is a nightmare, and everything is distorted.-A black cat
I wonder if the "spiritual lubricant" is the desire to have and take care of a child. Fefu's continued feeding of the cat, combined with its repulsive nature, points to the obligation to take care of one's child, no matter their character or behavior. Of course in the play, she's dealing with a cat, not a human, and the cat is not hers. Still, she's stuck in an absurd situation, where the idea of being a caretaker takes precedence over the nasty experience of caretaking. The repulsive cat does not unbound Fefu from her caretaking instinct (and perhaps more importantly, societal expectations for caretaking). This behavior seems to pull her closer to the traditional model wife character, and Fefu's strange relationship with her husband pulls her away. Fefu's experience with the cat is one of the few moments where she is not portrayed as striving towards masculinity. She is stuck between the masculine and feminine.
