“The most masculine of cats,” tout defenders of the breed, and they are indeed rugged, solid creatures who look as if they ought to be de-mousing a lighthouse on the stormy coast of Maine rather than sprawling on the settee. That is, after all, what they were probably bred for. Picture a cat, a large one, with tufted ears and a lumbering gait and a cheerful disposition; a coat with an undercoat of insulation, and oversized paws fit for trampling snow or scurrying up a tree trunk. Drooping whiskers, a propensity to sprout extra toes on his feet, an unusually expressive tail, and a dour, owlish expression that is almost a pout complete the Maine Coon, a creature on the cusp of entering America’s national pantheon of icons.
