A dilute tortoiseshell is a coat pattern, not a breed. Instead of black and orange, the cat shows soft blue-gray and cream in patches or a fine marbled blend, thanks to a dilution gene inherited from both parents. Nearly all are female, because the patchwork depends on two X chromosomes. Most are domestic shorthairs or longhairs, though the coloring also appears in Persians, British Shorthairs and Maine Coons.
That mix of backgrounds means a dilute tortie can be a compact short-haired apartment cat or a fluffy long-haired one who needs regular brushing. Talk of "tortitude" has little evidence behind it, so meet the cat in front of you, whether she turns out shy, outgoing, cuddly or independent. Shedding is moderate, and most weigh between 6 and 14 pounds.
