Hartz Flea and Tick Drops for Cats and Kittens to be Phased Out

At EPA’s insistence, Hartz Mountain Corp. has agreed to cancel uses of several flea and tick products that may be associated with a range of adverse reactions, including hair loss, salivation, tremors, and numerous deaths in cats and kittens.

In the short term, the agreement calls for new labeling of the products. The new labeling will state that the products of concern are not to be used on the most vulnerable animals, including cats and kittens that weigh less than 6 pounds, cats older than 13 years, or kittens less than 5 months old.
