My cat Fuzzy has the worst dandrff and clumps right above his tail. He is an outside cat and has ouchy claws . when I try to brush him he gets all playfull and attacks me then he takes off running to the basement or outside ... I tryed inclosing him in a room while brushing him but he freaks out meowing and running away and scratching me . What can I do to brush him without him having a spaz attack lol .

ps hes a long haired cat.
