Refers to a reddening of the coat color, especially the ground color in brown tabbies. May be a polygene or the result of the action of a group of polygenes. Considered desirable in the Golden. The rufous factor changes the drab beige 'yellow' band of the wild tabby to a brilliant apricot; it changes the drab orange to a brilliant, rich red. The Ruddy Abyssinian is a rufoused black agouti tabby.
