The beloved American poet Carl Sandburg wrote one of the world’s most famous cat poems—though it really isn’t about cats. It is “Fog,” published in 1916, and brief enough to quote here: “The fog comes / on little cat feet. / It sits looking / over harbor and city / on silent haunches / and then moves on.” People who have never heard the name Carl Sandburg have certainly heard of fog coming “on little cat feet.”
