You might be familiar with the Coats and Clark Company, a maker of thread. Back before Coats and Clark merged, Clark’s Thread hit upon a rather obvious advertising ploy: show an adorable kitten playing with the thread. (After all, everyone knows that cats and kittens like to chase strings and threads.)
The idea caught on, and other thread companies used cats in their ads. The Corticelli Company, for example, showed two adorable white kittens frolicking with spools of thread of all colors, with the slogan “Too strong to break.” In their day—the ﬁrst decade of the twentieth century—the Corticelli kittens were among the most famous ad cats in the world.
