Query: Read This Before U Buy

In 2005, the EPA canceled permission to use phenothrin in several flea and tick products, at the request of the manufacturer, Hartz Mountain Industries.[1][2] The products were linked to a range of adverse reactions, including hair loss, salivation, tremors, and numerous deaths in cats and kittens. In the short term, the agreement called for new warning labels on the products.As of March 31, 2006, the sale and distribution of Hartz's phenothrin-containing flea and tick products for cats has been terminated. However, EPA's product cancellation order did not apply to Hartz flea and tick products for dogs, and Hartz continues to use phenothrin in a concentration of 85.7% in many of its flea and tick products for dogs.[3]I bought this as a quick solution, and thank heavens I read reviews before applying to my beautiful Yorkie. <3
