It took several weeks, but the dandruff cleared up completely on my 15 year old cat. Her glossy fur now gleams and she doesn't scratch as much. I also have two four-year-olds. Their coats have become softer, glossier and very healthy looking. I'm sure the quality of their coats reflects all the health benefits of this product.
