Almost Killed My Cat

I boycott any Hartz products because of my experience with the flea drops. I applied the Hartz flea drops to my cat (who was a 6 year old, 20 lb Maine Coon at the time) and within an hour he became lifeless. In a panic I called my vet. I started to tell them what was happening, and I kid you not the vet tech on the line said “you used the suicide drops didn’t you”. They told me to hang up and immediately apply a whole bottle of blue dawn dish soap on dry fur. Then wet him and lather him up. Wait 5 minutes then rinse, then bring him in immediately to be given IV fluids to flush his system. Luckily he survived. Once home and settled I started Googling these drops. What I found was so upsetting. I don’t know how these drops are still on the market. I don’t know how they don’t change their formula. Hundreds if not thousands of cats have died or almost died from these drops.


We used Hartz flea spray and spot treatment on our 14 yr old terrier mix about 4 weeks ago. He got around good, played with the kids and loved to eat!!! He started to become weak, especially his back legs, stopped eating and drinking and also layed around and didnt want to so anything. We ended up at emergency vet this weekend and he was in kidney failure, with his age the vet disnt think he could pull through this so today we had to say goodbye to him. If I knew that these products did this to other animals, i would have never purchased it. Do you know how hard it is when ur 4 yr old says” i dont want decter to die mom..

My cat just died because of Hartz

From Staci via email:

I’m desperately trying to get the word out about the dangers of using Harts. Until Friday, I had never heard about how dangerous Hartz flea drops are. Three weeks ago, I applied Hartz Ultraguard to both of my cats. Soon after, my 12 year old, Jackson started having strange leg spasms. It was like something was shocking him, and he would take off running. Then he stopped eating and became lethargic. I thought he had grown tired of his food, so I tried several different brands. He would take a few bites and stop. Then he started drinking a lot of water. The weight loss was rapid. When we took him to the vet on Friday morning, I expected to hear that he was diabetic. Instead we were told that he was in acute renal failure and severely anemic. The vet explained how many animals that she had personally seen die from Hartz flea medicines. I had no clue that buy switching to Hartz to save a buck, would cost me my furbaby. There was no hope of recovery. We took him home so that the kids could say goodbye when they got home from school. A little before 5pm, he took his last breath. Now my spunky 16 year old healthy bobtail is showing some scary symptoms. She had become very vocal tge night after the application, but I didn’t make the connection. Now she’s vomiting everything she eats and is starting to drink a lot of water. I will be taking her to the vet, today, and praying for the best. I’ve filed complaints with the EPA. I’m plastering Hartz Facebook with my story and pictures of my baby. Why isn’t this on the news? Most people are completely unaware that they could be killing their beloved pet. How can we get the word out? How can we make sure that Hartz is held accountable? My heart is broken because I unwittingly killed my baby. I don’t want anyone else to go through this.

Beautiful 1-1/2 year old Chocolate Lab gone in 5 hours!!!

Our chocolate lab, Serenity, was only 1-1/2 old when something went horribly wrong.  At first we thought she might have ingested rat poison due to her sudden symptoms and how she died, but after researching on the internet I came across this web site and was shocked to see so many other sad stories that were very similar to mine.  What happened was we were awakened at 1:30 a.m. by my son who said the dog was crying in her sleep, went into a seizure and fell off the couch on to the floor.  When I first saw her she was lying on her side, breathing very shallow, and her eyes were open, but did not look focused.   I thought maybe she had had a grand mal seizure and was in a post ictal state so we sat near her and waited to see if she would come around.   She did start to come around, but she just did not look right.  Then she started having diarrhea with a little bit of blood in it, and she vomited twice (no blood in the vomit).  The diarrhea continued, but  it got to the point where there was just blood coming out.  After 4 hours of profuse rectal bleeding she collapsed on her side and started yelping.  We called our vet at about 6 am and he said he could meet us at his office in a half-hour.   Unfortunately, it was too late.  She just laid on her side and continued yelping for next 40 minutes

Sorry for the downtime and lack of posts (spammers suck)

Hi y’all,

Sorry for any downtime, lack of user stories, and the inability to create an account and post your story here on Running this site has been a 15-year side project for me, with the goal to have a one-stop place where victims can learn about the dangers of Hartz flea & tick products (as well as other over-the-counter products), and the ability for you all to share you stories, photos, and connect with each other. Unfortunately, spammers & bots like to try to take website down because they have nothing beneficial to offer society. I couldn’t begin to tell you how many times has been hacked, and how many thousands of spammers have registered for this website. Over the years, the spammers have *almost* brought this site down to a crippling halt. Almost to the point where I was just going to chuck it, or just leave it, in all its hacked and spammed up state to just become a junky void of spaminess.

But, alas, I decided against just letting it go. You can now register with the site again, post your stories and comment on each others’ stories. If you have any issues registering or posting your story, just email me at josh at hartzvictims dot org.



NRDC Files Petition for Review To Ban Flea Collars and Pet Products Containing Pesticides


In February 2014, NRDC filed a petition for a writ of mandamus in the United States Court of Appeals for the District of Columbia Circuit seeking the court to compel EPA to respond to NRDC’s petitions to cancel all manufacturer registrations and uses of propoxur and TCVP, which are used in pet flea treatment products. Sergeant’s Pet Care Products, Inc., Wellmark International, and Hartz were among flea collar brands at issue.

Products, Inc. and Wellmark International, whereby the companies voluntarily cancelled the use of propoxur in flea collars. Related uses of other chemicals, including TCVP in pet collars, were not addressed in that agreement, and EPA denied, in November 2014, NRDC’s 2009 petition seeking to cancel all pet uses of TCVP. NRDC first petitioned EPA to cancel propoxur uses in pet collars in 2007.

Mac’s story

Via email from Callie:

Mac was a beautiful, healthy, happy male cat. He was 9 years old and had more energy than any kitten!
He spent most of his time outside which led to him contracting fleas.

We decided to use the Hartz flea and tick collar. Mac had his collar on for approximately 1 week. I noticed he seemed agitated and itchy so I removed the collar. When I removed it I noticed a gross chemical burn that was all the way around his neck. We tried to help the itch go away because we thought that was his problem, little to our knowledge there was much more going on.

Mac passed away today (December 12th,2014) due to kidney failure and failure of of his nervous system. I did some research and Tetrachlorovinphos, which is one of the chemicals in the collars, is actually known to attack the nervous system.

This needs to stop! I can’t imagine the pain my poor cat went through and it’s heartbreaking not being able to help your pets when they need it. Please people let’s stop this horrible product from harming others!

The picture attached is of the chemical burn once it finally started to heal. As you can see the chemical burn was layers and layers into his skin.


Another Hartz Victim :-(

From Jennifer via email:

December 8th, 2014

I was babysitting a kitten who had fleas. I have 3 older indoor cats of my own and I didn’t want them to be infested with fleas and since I was looking at 4 cats that I needed to treat, I was looking for something that I’ve used in the past and had no issues with. I hadn’t used the Hartz UltraGuard before, but I didn’t have another choice that was in stock. I grabbed two boxes and checked out (at Target). Upon arriving at home I held down the first cat, my beloved Goliath 🙁 He was first and the only one that had a reaction. I noticed that he became withdrawn and wouldn’t come near me. I thought, “it’s okay, he’s just mad that we are holding “Missy” as a temporary foster until the storm passes (an outside adoptee cat).

December 11th, 2014

As I sat on my couch getting ready for a conference call, Goliath came up to me and wanted to cuddle. I ran my hand down his head, past his neck, to his upper back…. and I stopped. That’s when I realized that HIS FUR WAS MISSING!!! OMG! I jumped up and ran him into the bathroom to take a closer look. I had left my phone in the living room and shouted for my son to get it for me to immediately start taking photos. Goliath wouldn’t let me touch his wound. It was red and sensitive. I grabbed my pain relief neosporin and tried to put it on his neck, but he kept trying to bite me (and that’s not like him to bite at all). Goliath is literally my gentle giant, but as soon as I tried to do anything with that spot on his neck, he absolutely refused and fought me. This I knew was painful for him 🙁 I felt absolutely helpless. I called our 24 hour vet and she said that I could give him a bath if he let me… so I tried. And it was another fight. A cone or bandage wouldn’t help him because it would have to touch his neck. But again, all I could really do is sit and wait and make sure that it didn’t blister.

Now that we are waiting for the update on how everything turns out, I have posted the attached photo to my social media to let others know what happens when you might say that it won’t happen to YOUR pets. This is absolutely real and heartbreaking for me and others (now that I have seen what the company fails to tell people). If I had known that this was going to happen, I would have taken the time to spend the $100+ for flea medication that wouldn’t harm my beloved animals.
