"Come on in and show us those snappy snappies." - Peach Wilkins
- "I got me a handsome collection of felines, topside, of all shapes and sizes. Ain't no woman alive could part me from my pussy cats. And here's ol' Andy Ryan tryin' to tell me I can't bring my babies down here?"

Cats are small domesticated mammals. They were a logical animal to have in Rapture. Not just as pets, but for the inevitable task of vermin control. Several are encountered in the BioShock series, but all, except those in Paris, are dead.
Audio diaries made by Oscar Calraca indicate that cats were initailly illegal in Rapture and had to be smuggled in. It seems after the influx of felines, the law was relaxed. The number of cats in Rapture was sufficient enough that there were multiple businesses dedicated to the production of cat food.
