You can't beat World War II for crazy technological innovations. People worked on anything from shark repellent to exploding rats to bombs that would drift across the Pacific ocean on the wind. Unfortunately, there were also cat bombs.
This page from a 1584 treatise on explosive weaponry reveals two of the 16th century's more mobile methods of destruction: the cat bomb and the bird bomb, apparently used to set buildings on fire. BibliOdyssey has more fiery weapons from this manuscript, the rest of which are safer for friends of felines.
In a disturbing story (that comes with a happy ending!), the bomb squad of Amherst, New York responded to reports of a suspicious package but instead of figuring out which color wire to cut, they found a living cat sealed inside the box.
A suspicious, bomb-like package was spotted in front of a Social Security Office in Florida. The bomb squad was sent out to defuse the situation but when they arrived, they found out the "bomb" was actually a box filled with kittens.
