Project Acoustic Kitty: The CIA’s Cold War Feline Secret Agent

by Austin Lee

Project Acoustic Kitty was a real CIA initiative in the 1960s during the Cold War, aimed at using cats as covert listening devices to spy on Soviet officials. The plan involved surgically implanting a microphone in a cat’s ear canal, a small radio transmitter at the base of its skull, and a wire antenna woven into its fur to record and transmit nearby conversations. 

The project, developed by the CIA’s Directorate of Science and Technology, cost an estimated $10–20 million and took five years to execute due to the technical challenges of miniaturizing the equipment in an era before microchips.

The idea stemmed from the observation that cats could move unnoticed in public spaces like parks or near embassies, making them theoretically ideal for espionage. The first field test, however, was a failure. 

In 1967, a cat was released near the Soviet embassy in Washington, D.C., to eavesdrop on two men in a park. According to several accounts, including former CIA officer Victor Marchetti, the cat was hit and killed by a taxi while padding across the street with its license to listen. Former CIA technical officer Robert Wallace disputed this, though, in 2013, claiming the cat was unharmed, and the project was abandoned due to the difficulty of training cats to follow orders. 

A declassified 1967 CIA memo, titled “Views on Trained Cats,” acknowledged that while cats could be trained to move short distances, the “environmental and security factors” made the technique impractical for intelligence purposes. The project was canceled that year. 

The Acoustic Kitty was not alone. Over the years, other animals have worked with U.S. security agencies.

In the Old West, the U.S. Army Camel Corps played a role in capturing a notorious bandit.

In Soviet-occupied Afghanistan, American mules moved through the mountains like smugglers with a vendetta, hauling the war on their backs, one surefooted step at a time.

In Washington, D.C., a cat is among the K-9’s who protect the Defense Department. The working cat Minou reached out personally to Soldier of Fortune to confirm that she works at the Pentagon.

Historical references to Acoustic Kitty surfaced when CIA documents were declassified in 2001, revealing details through the National Security Archives. Sources like The Wizards of Langley by Jeffrey Richelson and Frankenstein’s Cat by Emily Anthes provide detailed accounts, with Marchetti describing the cat as a “monstrosity” due to the invasive surgery. 

The CIA’s own website confirms the project, emphasizing that the cat was not mistreated and that the procedure was humane, countering myths of a “Frankenkitty.” Despite the failure, the project reflects the CIA’s creative, if impractical, Cold War surveillance efforts, alongside other animal-based espionage like pigeon-mounted cameras.
