You can't really tell with pictures but I think Mickey's coat looks wirey to me.. Is it rough? But his head doesn't appear to be that way??? Minnie looks silky. Do any of their coats get matted quickly? if they do then that would be a sign of Cotton, also if you bring them into a dark room with all the lights shut off you can see what color their eyes glow, when you put a flash light on them. That is supose to tell you what their coat is.. Not sure if it works though, as my Bell glows yellow and she is cotton and my Lilly glows yellow and she isn't, she has a wire coat.(but it might be becasue she is still very young)
