Kitten by Stacey Yu

Katie hasn't spoken to her mother in a year when her boyfriend James introduces her to his cat Silver. A small, vulnerable, incorrigible ball of need, Silver's acceptance of Katie cracks open something inside of her: an unravelling begins. Fresh out of college and far from home, Katie is desperate to skirt the demands of adult life - especially because, as she promised her mother, the plan was to never grow up in the first place. Luckily, she has James: self-assured, generous, and seemingly happy to make decisions for them both. When they go on holiday to James's family's seaside home, Katie's attachment to Silver grows. Silver doesn't mind that Katie can't seem to get a job, hold her own at dinner parties, or make amends with her mother. Silver, who gets to misbehave spectacularly, be childish, be gross, and still get fed, seems to have the life Katie increasingly longs for.
