My name is Cat, Acoustic Cat

Acoustic Kitty was a CIA project launched by the Directorate of Science & Technology in the 1960s attempting to use cats in spy missions. A battery and a microphone were implanted into a cat and an antenna into its tail. Due to problems with distraction, the cat's sense of hunger had to be removed in another operation. Surgical and training expenses are thought to have amounted to over $20 million.
