our cats (3) were mistakenly poisoned today because the plastic vials of flea medication looked exactly like other tubes that we have used in the past just for cats & kittens (which instead were for our huge dogs). There was no labelling on the products to indicate that it was lethal or deadly or any sort of indication to NOT use on anything other than dogs. All three cats are now on IVs and anti-seizure medication at the emergency vet clinic. These vials were made by BioSpot which I believe is made by Hartz … other vials of flea medication for myST. Bernards is in large tubes (duh) and the labels are easily read (frontline) …however, these three small tubes were virtually illegible as to any labels but with a magnifying glass, we could read (after the fact) that it was for dogs 60 lbs and over, etc. …. still nothing said about cats. However, we immediately began cleaning and tryign to remove this product from the cats’ coats; all to no avail, within 5-7 hours, they all began exhibiting symptoms of toxicity. Is there any kind of suit that can be brought against Hartz for this negligent labelling that causes such accidents to occur?

any help you can give us woudl be greatly appreciated. so far, after 10 hours of the occurrence, they are hanging on for their life, but just barely. please let me know if there is any help or advice from others.

My dog got mange from Hartz products!

The begining of last week I found one flea on my dog, that has never ever ever had fleas. I freaked out and ran to Wal-Mart to buy some flea drops so I could get something done ASAP. I work during normal business hours, so I’m unable to get to the vet during the week. I applied the drops as instructed and thought nothing of it. A couple of days later I started to notice these little bumps on my dogs side, they were filled with puss, gross I know. Then Monday when I arrived home from work, I noticed that since that morning my dog had lost a patch of hair. I called the vet and they prescribed some medicine and I decided to take off of work to take my dog to the vet. I went to the vet and they did some tests and said that my dog has mange! I told them about what I had put on her and they said that is what caused it. I was shocked! I thought only dirty nasty dogs got mange. They said this was an autoimmune disease like from the inside, or something I don’t totally understand that part, but I do understand that this product — Hartz Advanced Care Plus Drops — Did this to my baby! I’m am very unhappy. I called their customer relations dept right when I got home and they requested all kinds of documentation from my vet, which I have requested from my vet, so I’ll hopefully be getting that in the next week. Then I’ll be mailing it to Hartz. If anyone has any more information or knows of any sites I can go and read up about this happening to dogs please e-mail me at [email protected]

If there is some sort of lawsuit I would like to know more about that too, if you can direct me towards a page where I can learn more about it.

Thank you for your time.

Hartz Flea and Tick

My darling little 14 week old kitten went into tremors and shock after applying a flea product made by Hartz. Is there not a class action lawsuit against the manufacturer?

Update on Class Action

May 29, 03
The class action law suit filed against Hartz by the law firm of Faruqi & Faruqi on behalf of one individual( sorry name withheld) The unnamed individual and Hartz have decided to terminate the lawsuit and fully settle all claims which are or could havve been asserted by the unnamed individual, upon the terms and conditions set forth in a Confidential Settlement Agreement.
The Confidential Settlement Agreement may also entitle you to certain benefits from Hartz upon satisfaction of certain conditions. You will need to get the affidavit, from the Law firm, fill it out , have it notarized and sent to Consumer Relations Dept., Attn: Dr. Jill Richardson
The Hartz Mountian Corp 400 Plaza Dr, Seccaucus, New Jersey 07094
no later than July 31, 03. Hartz will send you a general release to sign and return, They will reimburse for the cost of the product and reason and related vet expenses

This means Hartz will still be causing serious injury and possible death to cats that this product is used on.

Many are refusing to go along with this “settlement”
You may want to read the EPA’s report.

There is a new group forming at Yahoo’s groups FelineOwnersAgainstHartz-

Hartz has to be stopped before anymore animals suffer from their flea products.

Another potential law suit

My neighbors found a cat and brought it to me. I put the Hartz product on the cat and within two hours the cat was experiencing grand mal seizures.

My vet bill is expected to be over $1,000.00. The cat is presently at an emergency clinic and I will have to pay double tomorrow since it is Easter.

I work for a law firm and was going to simply put this matter immediately in suit via small claims court (any matter below $3,500.00 qualifies).

To Whom It May Concern:

I am writing to issue a formal complaint about your Hartz Advanced Care Brand Flea and Ticks Drops Plus and to request reimbursement for our veterinarian bill.

On Thursday, June 21, 2001, my fianc? and I bought a three month supply of the above mentioned product from a reputable pet supply store. We applied one tube of the product, as directed, to our cat?s back at approximately 12:30am on Friday, June 22, 2001.

I awoke at 7am that same morning to our cat crying, shaking and delusional. We called our veterinarian immediately and were instructed to wash our cat and bring him in as soon as possible. We followed the vet?s instructions and brought him in.

Our pet was sedated and given intravenous medication throughout the day. The cost for this treatment totaled $88. I have researched and documented numerous instances of this exact same occurrence with other people and their cats. Nowhere on the product?s box do you give warning of any reactions.

Again, we followed the instructions provided and feel that your company is liable for mislabeling your product. We expect a full reimbursement totaling $98.74.

Vet bill $88.00
Hartz Advanced Care $09.99 + 7.75% sales tax
Total $98.74

Class-action law suit filed against Hartz

Via News
8 Austin

11/30/2001 4:15 PM
By: Kelly Kyle

The Environmental Protection Agency continues an investigation into Hartz flea and tick products, while a pet owner has filed a lawsuit against the company. 

Austin veterinarian Dr. Christine Duvall has seen some of her patients die from what she believes was a bad reaction to over-the-counter flea and tick drops.

“Over-the-counter flea products have been a serious problem for a couple of years now and I’m surprised at how long it’s taken for things to occur, but now there’s finally a lawsuit happening,” Duvall said. “The EPA is finally getting involved and hopefully very soon there’ll be something done and possibly pull these products off the shelf.” 

The Hartz flea and tick drops are one over-the-counter medicine that has caused some pet owners to take their complaints to a court of law. Faruqi & Faruqi, a New York law firm, has taken on the task with a class-action lawsuit. The lawsuit claims that one woman’s three cats nearly died after one application of the drops. 

“She is very concerned with the other individuals who are out there and essentially wants to get this product off the market,” said Anthony Vozzolo, a lawyer with Faruqi & Faruqi, through a phone interview.

The lawsuit comes two months after the EPA completed a review into thousands of cases of pet illnesses and deaths after use of Hartz flea and tick drops. 

The EPA tells News 8 Austin that the review into Hartz flea and tick drops is now an, “enforcement investigation” into whether Hartz Mountain Corporation has violated federal law. 

Hartz voluntarily paid some pet owners’ veterinarian bills incurred after using the products in question, but the corporation continues to stand by all of its products. 

Dr. Albert Ahn, a veterinarian for Hartz, said the lawsuit is not a concern. “We don’t comment on specific litigation, but in any event we will be defending ourselves vigorously and we feel quite confident that we will prevail,” he said. 

Nearly 100 pet owners nationwide have contacted the firm with complaints about the products. Hartz continues to wait for the results of the investigation which the EPA expects will last a few more weeks.
