I make my own flea shampoo and it kills all the fleas on the animal ,, Just give em a bath let it set on them for 15 min rinse ,, NO FLEAS, IT COST ME LOTS TO MAKE BUT IF IT WORKS ITS WORHT IT ,, Can ship for 5$ more ... dont waste your time with the stuff in the store it dont work ... THANKs to all the people who love my soap,,, i want to some day have it in the stores for every one... its enough to do like 6 med dogs and 10 cats .. but less is more .. dont scrimp on it if you want to live with out fleas on you dogs and cats ...
