Hello my story is very similar, I purchased those drops abouth a week ago, followed the instructions, then my cat was a little weird abouth a hour later, but i did not worry too much abouth it, next day he was almost in a drunk status, still i was sure he was having a small alergy reaction, next day when i came home he was having convultions and vomiting blood, there was not much else to do but to put him down, HARTZ… you may want to put on the back of you’re products MAY KILL YOU’RE CAT….
My cat was my friend for over 3 years. Please take these drops off the shelves…

I had grown up buying Hartz flea collars for our many dogs and cats and had always trusted the product and company. So, when I discovered that Hartz made a flea/tick drop medication which was much cheaper than the competition, I decided to try it on my two cats yesterday afternoon. The younger cat (3 yrs.) seems fine, however, my older cat (10 yrs.) is drooling, frightened, is losing her hair, is incontinent and not eating. Last night she had a high temperature as I could feel it as she pressed against me. I am afraid for her health and even more so after reading the many, many similar stories online by other concerned and duped pet owners. HARTZ TAKE THIS PRODUCT OFF THE MARKET!!! YOU ARE KNOWINGLY INJURING PETS! P.E.T.A. WILL BE GETTING A LETTER FROM ME ASKING FOR THEIR HELP IN FORCING THIS PRODUCT TO BE REMOVED.

I lost my Dog of 8 years today due to hearts ultra guard spay from her licking herself, she went into liver toxic state and died after spending $300.00 on vets, Hearts needs to be removed as does the bio-spot’s both are killing cats and dogs due to the pesticides used!

To all who have posted on this thread: I am terribly sorry this has happened to your pets and your families. It is truly a tragedy. Hartz Mountain Corporation has a deplorable safety record over the years. They aren’t the only manufacturer with an unacceptable safety record, but since your problems resulted from Hartz’s products you should know that their appalling history goes back to the late ’80’s and ’90’s when their product, Blockade, was pulled from the market because of an unacceptably high number of pet injuries and deaths, including human deaths. It was later reintroduced and again had serious safety problems. Hartz was cited and fined for not accurately and promptly forwarding consumer reports to the EPA as all manufacturers (and registrants) are required to do by federal law. In the early 2000’s they were required to make numberous package labeling and directions revisions on both their cat and dog insecticide ingredient products. In 2005 the EPA, probably the most lax oversight agency in the federal government, forced Hartz to terminate their cat and kitten products, issuing a Cancellation Order against Hartz’s products containing pesticide ingredients. The number of cat and kitten injuries and deaths was stunning and even the EPA could no longer ignore it. Please also report this incident to the National Pesticide Information Center, at 1-800-858-7378. They maintain a database of pesticide-related illnesses for the EPA. The EPA uses this database to determine if dangerous pesticide products require specific action in terms of safety requirements, including up to removal from the market. Don’t let Hartz get away with the devastation they are causing any longer. They count on victims’ owners taking no action or simply complaining for a week or two and then going away. Please take the time to report this terrible tragedy to the NPIC. Again, I’m very sorry this has happened to you. I have a friend who also lost a perfectly healthy dog as a result of these pesticide products and I’ve seen first hand the damage and devastation they have caused. It’s terrible…particularly since it’s avoidable if Hartz–and other manufacturers–and the EPA were truly concerned about pets and pet owners.

I don’t know what to say! My boyfriend brought me this product last January from LA. My cat experienced some acne problems for two times and this vet gave her many pills. It was really hard to gave her the tablets as she refused to eat the pills. Only my mom could have her the medicine by syringe! But when I used the product for the first two months all the skin problems gone safely!
I used the 3rd shot, on June when I saw some spots! And they gone! But she was depressed and has irritation a lot! Just today I found some spots on her head and was trying to order hartz which I saw above comments. OMG! I feel terrible! All the cats are at the same age as mine and I know how it hearts! Now what should I use as replacement! Please give me an advice!

I wanted to know has ANYONE had a good/okay experience with this product i just used it on my 2 6 mth old puppies and i just started to search to see how fast it works and im getting all negative. i’m really worried now.

I use it on my cats with no issues, ever… I used to use it on my dog too before she died of old age spring of 2011. I think this is a case by case basis because personally I have never had an issue with it, my cats have been on it all summer and both of them are completely normal, as they were last year, and the years before that.
