Ok, I'm with woadtoad! I have 2 cats, one 9 yr. old female who has never had dandruff, and a 6 yr. old male (black) who has dandruff quite often. They both eat the same food, so its hard to separate feeding times. All I do to help the dandruff, is dribble about a tbsp. of OLIVE OIL on their dry food every day. This totally helps combat the problem, and there is no worry of my senior cat getting too fat!! It is healthy for both of them and cheaper than buying 2 types of food @ $45 a bag!!
