Need Advice

Hi! I gave my cats a treatment last night. I noticed that one is acting distant. His ears were flicking and he had some slight twitching. It is impossible to bathe these guys, so I tried wiping it off a bit. They are both still a little distant, but I haven’t seen any twitching. Should I still worry? I have reached almost 24 hours since treatment. Though they are acting distant, they aren’t twitching. Advice???

Within 24 hours..

Please read this and beware! Just a week and a half ago, I gave my cat a flea and tick treatment: Hartz Control Spot. Within one hour she went into seizures. I rushed her to the animal hospital and withing 24 hours she died. “Zoe” was only two and a half years old..was an indoor cat and the love of my life. As soon as I arrived with her at the animal hospital they asked me if I had used the Hartz product on her..of course I said yes. I was later told by my Vet that the product should not be on the market and that it was very toxic to many cats nervous systems..due to the ingredient “permethrin”. He also said that he had contacted all of the merchants in my immediatae area and asked them not to carry this product due to its potential danger to cats. My Vet and all of his assistants did everything they could to save Zoe..but they were not able to. I am very determined to do something about this situation. Nothing is going to bring my pet back..but the satisfaction of trying to get this product off the shelves will help ease some of the pain. I did contact the Hartz Corp…and sent them the information they requested. I have no idea what they are going to do or offer, but know that even if they were willing to pay her hospital wouldn’t be enough. I want only to have this product banned from shelves any and everywhere. No one…and I mean, NO ONE should lose thier pet by “caring” enough to give them a flea and tick treatament. My heavy heart wants some kind of justice for this injustice. Please, not only DO NOT buy this product..spread the word to anyone you know who has a cat or kitten. This situation is just so unbelievable to me…and so unfair and sad. One day I have a beautiful loving cat..the next day I am making her a grave marker.

Hartz Flea Collar Caused Seizures

About one month ago I bought a Hartz Control Flea and Tick collar at Wal-Mart for my dog Roger. He is a 9 year-old Australian Shepherd. I put it on him that night and thought nothing of it.

Three days ago Roger had a gripping seizure. He was calmly snoozing at my feet one minute and convulsing, frothing at the mouth and stiff the next. To our knowledge, he’s never before had a seizure. I took him to the vet’s yesterday and he checked out okay. After some advice to look up the chemicals in the collar online, I found that one of the main ingredients, tetrachlorvinphos (an organophosphate), has been known to cause several side effects in both cats and dogs. I’m convinced this is the cause of Roger’s seizure and immediately removed the collar upon becoming knowledgeable of the effects.

Roger hasn’t had a seizure since, though it’s only been three days. However, I’m praying that since removing the collar, he won’t have another episode again. After perusing this site and the horror of my own experience, I certainly won’t be using any Hartz products, and I will be sure to warn others.

Bad Reactions to Hartz Flea Drops for Cats

I applied the Hartz Advanced Care Flean Tick Drops for cats a few days ago to my four housecats. All four are not related and are different breeds and ages. I followed directions precisely and almost immediately starting seeing my cats acting strange. One in particular (my biggest cat) had the worst reaction. He started running around in a panicky state and then burrowing himself under the couch cushions and would not come out. I got online and started researching only to find out about the lawsuits and all the other horror stories. I washed it off as best i could from all four cats and watched. I am a lucky one. After about three days of some erratic behavior but no seizures or convulsions it appears my cats will be alright. As of now i have two cats with complete bald spots on the back of the neck where the drops were applied with redness.

I am so angry that this product is on the market! I have gotten busy writing The Hartz Mountain Corp, and every other store that sells these products. So far i have heard back from Hartz which actually stated and i quote “they had no reason to believe there would be an adverse reaction”. Can anyone believe that? After they have been going through lawsuits for years?

I wrote them back stating i couldnt believe they said that in their letter and we will see what they reply.

NOW THE GOOD NEWS! I went into my local Winn Dixie Grocery store where i purchased the product and told them my story and was SO pleased they immediately got a shopping cart and took all the hartz flea products off the shelves! It felt so good to DO something about this….im asking everyone to do the same. My daughter who lives in another state went into a local pet store who carried these products and did the same thing. THEY removed them! So it does work and if we can save any pets from this pain its worth it! So people dont just get mad…….get active!

I Poisoned my cat

I gave my 2 year old little cat the Hartz flea and tick drops (Phenothrin) in the morning. At the same time I gave my 10 year old cat the last dose of Revolution (Selamectin) flea and tick drops. I left the house for the day and when I returned that evening my 2 year old cat was experiencing hypersalivation and rapid breathing. She seemed uncomfortable and agitated. I thought she would overcome it so I let her be for a few hours and then started to worry when it continued. Meanwhile the 10 year old was fine. When I went on line I immmediately found a court case where a woman was sueing Hartz for damages and this site. I immediately washed my 2 year old in the sink in an effort to get all the medication off. She stopped the hypersalivation but is lethargic this morning and still is breathing fast. I will return the product to the store along with a copy of this web site to show that they should discontinue sales. I think she will be allright – should she see a vet?


These pictures are the most disturbing that I’ve ever seen. You have been forewarned.

Yes it is. Please see the attached recent photos of buddy taken on
7/26/03. My veterinarian has put her self on the line by writing hartz on
my behalf and I intend to do something about this produced being sold.

Sincerely Connie Stewart

Was this chemical burn due to a Hartz product?

If your pet suffers from Hartz poisoning

Someone on the FelineOwnersAgainstHartz Yahoo group posted this very useful link about what to do if your pet suffers from Hartz poisoning.
It’s on a veterinary clinic site, and they also explain the effects that the toxins in Hartz products
have on companion animals and what to look for:

Almost lost my cat

Like everyone else, I was unaware of the danger of Hartz Advanced Care flea and tick drops. After following the directions precisely as the packaged label stated, I noted within a few hours that my beautiful calico cat was suffering from muscle tremors. She was rushed to the vet where she was diagnosed with pyrethrin toxicity (yes from the flea and tick drops poisoning her!!!) She had generalized muscle tremors, was mostly unresponsive, had an elevated temperature and heart rate. She required immediate bathing, IV Fluids for 1 and a half days as well as several dosages of methocarbamol, a muscle relaxant. She continues to be pretty out of it and lethargic even 3 days home from the hospital. When I spoke with the Hartz corporation they were nonchalant to say the least……..I am now working on getting my “Pumpkin” back to good health and on alerting all pet owners that I know. I think mass emails would do nicely.

My Vet thinks

A few days after applying Hartz flea drops on our cat, we found him acting stangely. First, he kinda hid outside and would’nt come in the house. A few housrs later he came in, but pretty much stayed in the same spot for hours and would’nt eat. After two days of not eating, he finally took some milk. Then we noticed his pupils were completely dialated,and were’nt reacting to light. We took him to the Vet where he was given a complete blood test, which showed nothing wrong. When I told the Vet he started acting stange after the drops, he said it may be the cause. We had to have him bathed by a professional groomer, and the Vet gave him several shots to counteract a possible reaction. After three days, the cat still has fully dialted pupils, but is eating and drinking normally.I have to take the cat back to the Vet in a few days.I found the empty vial of Hartz drops and plan to take them with me. If this is found to be the problem, I intend for Hartz to hear all about it!!
