Operation Cat Drop is the name given to the delivery of some 14,000 cats by the United Kingdom's Royal Air Force to the remote village of Sarawak, in the British colony of Borneo in 1960. The cats were flown out of Singapore and delivered in crates dropped by parachutes as part of a broader program of supplying cats to combat a plague of rats. The operation was reported as a "success" at the time.
