Willie has had some bad dandruff the past few months, mainly by the base of his tail (his favorite place to be scratched) but he doesn't seem bothered by it. I really would like to clear it up if I can though, does anyone know what I can do about it? Mom asked why he might have it and I know it's usually food but I REALLY don't want to mention that to her since I made them switch him to the Felidae from Purina and don't want her to think that what I said about better food was false. Thanks for any suggestions!
