The American longhair is not a specific cat breed, although aficionados are encouraging cat fancy associations to recognize this unique feline. For now, the term American longhair is used to indicate a cross between a Persian cat and an American shorthair cat. American longhair cats are typically medium-sized, reflecting the size and weight of their parents. Their coats come in a variety of colors and patterns and in varying degrees of thickness. There is sometimes confusion concerning the American longhair cat vs the Maine coon cat. This stems from the description of the Maine coon as America’s original longhair cat.
