Johnsons Cat Flea Cleanse Shampoo By Johnsons

The product arrived well packaged and in good time. The shampoo has a pleasant oduor and easily applies to the cats coat producing a good lather. Issue for me is whether or not this product really works. I intend to use this 3 time weekly as I have 2 cats one of which appears to have a serious flea problem. So I guess to give a thorough review I need to be using the product over some time.
