We use Johnson's Baby Powder for furry roommate household. It acts like a dry shampoo, takes lank, slightly oily hair and particularly the half-long-haired and long-haired Tiger are then again fluffy soft, like small cotton balls and smell tender for baby (if you like that even so, I'm not so sure) ,
Preferably in the evening the cat carefully and thinly over the whole body, or only the straggly places dusting, leave overnight and brush out the next morning. There remain no residue or bright streaks and the fur is again quite fragrant as freshly washed.
