From his name and appearance you’d think Misty was a female. Misty is a dilute tortoiseshell. As coat color is sex linked in cats, tortoiseshell cats are almost always female. The color combination in tortoiseshell (and calico coloring) requires two X chromosomes. As females are XX and males are XY the only way a male can have tortoiseshell coloring is if he has an extra X chromosome, XXY. Misty is a rare case of a male tortoiseshell cat!
