Then Mystery definately doesn't need to be 'powdered'.
He is an indoor cat for the most part and doesn't get dirty. He picks up grass sometimes when I bring him out on his harness...but that is easy enough to remove. I would rather he kept his natural oils...he has enough dry skin!

Is is common for long haird cats to have a lot of flakes in their coat? He seems to have more in his coat than all my shorthairs. I was thinking that because his coat is long it traps more dry skin than the short coats do.
