In the 1960’s, the CIA reportedly explored surgically inserting microphones and transmitters into cats, a project dubbed “Acoustic Kitty.” Former CIA officer Victor Marchetti told The Telegraph that the project "slit the cat open, put batteries in him, wired him up. The tail was used as an antenna. They made a monstrosity." The first wired cat was, according to the Guardian, released for spying and took just a few steps towards its target before the cat was run over by a taxi. The CIA concluded that the project was impractical for intelligence gathering.
