Stop Company from Killing Pets with Dangerous Flea and Tick Products


Target: Bob Shipley, President and CEO of Hartz Mountain Corp.

Goal: Stop killing pets with dangerous flea and tick products

Hartz makes flea and tick products for dogs and cats that are sold in stores worldwide. However, these products can be potentially very dangerous for pets. Animal injuries have ranged from chemical burns, to seizures, to even death. But Hartz does not seem worried about the suffering it causes. In 2005, at EPA’s insistence, Hartz Mountain Corp. agreed to cancel uses of several flea and tick products that may have been associated with a range of adverse reactions, including hair loss, salivation, tremors and numerous deaths in cats and kittens. Hartz relabeled the products to say they were not for use on sensitive animals or cats or kittens under 6 lbs, over 13 years of age, or under 5 months of age. The company was told to take the product off the shelf.

But Hartz products are back, and still harming pets, especially cats. Hartz flea and tick products contain phenothrin, which is known to be extremely toxic (and very often, lethal) to cats, yet it is used in a product marketed for cats. The cats who have been affected or killed by Hartz products have suffered acute systemic phenothrin toxicity, which causes seizures, muscle tremors, skin rashes, lethargy, decreased heart rate, fluid build-up in the lungs, hair loss, blindess, and ataxia/neurologic symptoms, among other issues. It also contains Tetrachlorvinophos (TCVP), an organophosphate pesticide used to kill fleas and ticks. It is classified as a “likely human carcinogen,” and is known to be toxic to the human nervous system. Whereas cats are not humans, their systems are very sensitive and likely to react to this pesticide the same way as, if not worse, than humans.

Clearly, Hartz does not care about animals’ wellbeing. Some people whose pets have been affected are putting together a class action lawsuit against Hartz. tells some of the horror stories people and their pets have been through. The company has not taken care of consumers’ pets, and has caused massive pain and suffering to animals and their humans. Stop Hartz from selling its flea and tick products and killing pets.


Dear Mr. Shipley,

Your flea and tick products have caused a lot of problems for many pets, but especially cats. The primary active ingredients in Hartz flea and tick products, Tetrachlorvinophos, Phenothrin, and S-Methoprene, are all very strong pesticides, as you know. Incidentally, Phenothrin is known to be extremely toxic and often lethal to cats, so why are you using it in the products you manufacture for cats? The cats who have been affected and killed by your products have suffered acute systemic phenothrin toxicity, which as I’m sure you know causes major health problems such as seizures, blindness, ataxia, muscle tremors, and fluid buildup in the lungs. Tetrachlorvinophos is classified as a “likely human carcinogen,” and is known to be toxic to the human nervous system. Since cats are even more sensitive than humans, why is this chemical being used in a product manufactured for cats? These chemicals are more than likely going to cause problems for cats, yet you continue to put them in your products for cats.

You have been disciplined on at least one occasion and forced to remove your products from store shelves, yet you continue to put products that can severely harm pets on the market. For a company supposedly dedicated to pets, you seem much more dedicated to the bottom line. Please stop producing these toxic products and pull your products from stores before more pets are harmed.
