The most creative way to use a cat as a weapon happened in World War II. The United States’ OSS (Office of Strategic Services, the precursor of the CIA) needed a way to guide bombs to sink German ships. Somebody hit upon the inspiration that since cats have such a strong disdain of getting wet and always land on their feet that if you attached a cat to a bomb and drop it in the vicinity of a ship, the cat’s instinct to avoid the water would force it to guide the bomb to the enemy’s deck. It is unclear how the cat was supposed to actually guide a bomb attached to it as it fell from the sky but the plan never got past the testing stages since the cats had a bad habit of becoming unconscious mid-drop.

Note: the method of guidance has always been guessed. But recent documentaries show the cats inside of a bomb casing harnassed with a view like the pigeon-guided weapon. The only way the cat could have guided the bomb would be weight displacement left and right towards the target ship. No way a cat strapped to a huge bomb from altitude would ever work as it would cling on for dear life. Cats were also used by the CIA postwar in "Operation Acoustic Kitty" which placed a bug in each cat with an implanted wire antenna through the tail! It took 5 years and 15 million dollars and on the first trial in Washington against a Russian target the cat got hit in the street while crossing! End of program!
