YMMV / The Cat Who... Series

• Development Hell: The Cat Who Smelled Smoke, the planned 35th installment (including special projects) in the series. Originally scheduled for 2008, then 2009, then canceled.
• Fanon Discontinuity: Book 29 (The Cat Who Had 60 Whiskers) is widely regarded as this by many fans who were outraged at the sudden and unexplained changes (Polly's departure and the burning of Qwill's barn) to the well-loved landscape of the stories.
• It Was His Sled: Combined with Late-Arrival Spoiler, seeing as how the majority of the series takes place after the fact. Poor Aunt Fanny....
• The Scrappy: Polly. A lot of readers found her jealous behaviour (and the fact that Qwill forgave it every time) to be incredibly grating and unrealistic.
• Seasonal Rot: The later books in the series were widely panned by both professional critics and consumer reviews, due to shoddy plotting and characterization. Many suggested that these installments were being written by a ghostwriter, though it was more likely due to author Lilian Jackson Braun's advanced age — she was born in the 1910s, but these books kept coming out until the mid-2000s!
• Values Dissonance: In The Cat Who Turned On and Off, Qwill finds an unpublished novel by one of the murder victims that brutally reveals the secret lives of his neighborhood's residents, which include a drug dealer, a bookie... and a "sodomite." Possibly slightly defensible as characterization, considering that Qwill, a middle-aged man in the 1960s with a somewhat working-class upbringing in the midwestern US, probably would not have especially sympathetic views toward homosexuality, but still jarring to a modern audience.
