Dilute tortoiseshell is a coat pattern, not a breed. Where a standard tortie blends black and orange, a dilute shows blue-gray and cream in patches or a fine marbled mix. The softer shades come from a recessive dilution gene, and because the pattern depends on two X chromosomes, nearly all dilute torties are female. Most are domestic shorthairs or longhairs, though the coloring also appears in breeds such as Persians and Maine Coons.
That mix of backgrounds means size, coat length and temperament vary from cat to cat. Shedding is moderate, and longer coats need regular brushing. Torties have a reputation for sass, but the folklore has little evidence behind it, so judge the cat in front of you. Most weigh 6 to 14 pounds, live 12 to 18 years, and do well in the apartments and houses Omaha offers.
