Nursing-home worker Morgan (Judy Greer) fakes illness to get House's attention after the home's pet cat, Debbie, sleeps next to her. It seems that Debbie only pays a visit to people if they are about to die and does so with alarming accuracy. While House dismisses Morgan as a nut job, he is intrigued by her theory on the kiss-of-death cat, and sets out to disprove it. When Morgan falls seriously ill, he and the team are forced to get to the bottom of both mysteries. Meanwhile, Taub struggles with his finances and reconnects with an old high school friend at the clinic whose business successes present Taub with an entrepreneurial opportunity he had not previously considered.
