Do not ever, EVER use Hartz products on your pets

I am currently in college studying Veterinary Medicine. Hartz products are DANGEROUS. we specifically discussed that in class. They are known for making animals ill, and unfortunately–killing cats. Dogs can tolerate pesticides better than cats (even though it is dangerous for both). Harts flea and tick control products contain pesticides, Deadly for cats, dangerous for dogs. PERIOD. Hartz have many lawsuits against them, and they do need to be shut down. If you have any signs of adverse effects (which seems to always occur with EVERY Hartz products) discontinue use IMMEDIATELY. As a matter of fact, DO NOT USE IT AT ALL. Things that can occur are rash, itching, blisters, bumps, seizures,loss of appetite, fever, vomitting, etc. and even, unfortunately, death. If you need flea and tick control, for your pets sake, please use Frontline. It is the safest product, and Veterinareans number one choice for a reason.

So thankful for internet information

So, we are moving to Oregon and we needed to buy Flea Meds for our 7 rescue kitties. We didn’t have a lot of money so we were very thrilled when we found Hartz Ultra Guard Plus for Cats at a reasonable price. Hartz is, well its Hartz. Trusted right?

So we bring this stuff home and go to apply it to our cats. Thankfully my mother taught me to read everything. I was taken aback by the need to separate the kitties cause of grooming, call the vet, no its Sunday. Call Hartz, no its Sunday! I needed to know if I could treat them on the move, that night, in their carriers. So, I went on the internet and asked Yahoo answers. Treat them, don’t worry was the response I was getting. But then Laurie, a complete stranger got on and said NO! She informed us of Hartz! We researched! We are taking it back and spreading the word. Another 7 Kitties saved from the death trap of Hartz Flea meds for cats!!

Lost one cat and now my kitten is sick

We bought Hartz Ultraguard One Spot flea treatment for our 18 month old cat Sarah in October 2010 as it was recommended to us by the pet store. We treated Sarah and after about half an hour she started to twitch and breathe heavily, she was jumpy and nervous and I wiped her down as I was worried she may have managed to lick some of the treatment off her fur. She seemed to settle a little and we weren’t so concerned. The next day she wasn’t eating or drinking and sneezing a lot and had no energy. We took her to the vet that evening and were told she had become very anaemic and her blood count was down to 7. The vet kept her overnight and she was on intravenous fluids and had been given injections and tablets to kill fleas. The next morning we picked her up and brought her home and tried feeding her water and watered down food with a small syringe as the vet had advised. Sarah became progressively weaker and kept trying to crawl under the couch. She died in our arms at 3 am the next morning. We were devastated and it took us a long time to be able to have another cat. At this time we did not know that the flea treatment had harmed Sarah as the vet told us she had died from anaemia, heartworms and excessive flea bites.

About 6 weeks ago I found a little grey kitten under our dumpster and took her in. We named her Misty and she is our baby. Yesterday evening, Saturday October 29th, we noticed Misty scratching and we treated her for fleas with the Hartz Ultraguard One Spot as we were scared of having a repeat of what had happened to Sarah. Misty is now 3 months old. This morning at 6 am she woke us up and was twitching and breathing fast and jumpy. I bathed her immediately and she didn’t even fight me  which really scared us. After her bath she seemed a little calmer but was still twitching and breathing fast so I called our new vet who told us to take her over straight away. This was at 8:30 this morning. When I got her to the vet and told him what I had treated her with and that I had bathed her already he told me it was the best thing I could have done but she still was sick. She is now on a drip and being treated by our vet and I don’t know if she is going to have kidney or liver damage from this product.

Please, please don’t let anyone else’s pets suffer like ours have. I will post here again once I know how our Misty is and if she is going to be ok.

Close One

My husband and I purchased Hartz Guard Pro for our 11 month old cat, Poptart. She usually is very bubbly and snuggly. After applying the medication on her, she was very distant and didn’t want to be touched. She then started smacking her lips and salivating excessively and her skin became bright red. We tried wiping the medication off with a wet rag and called the Vet. The vet told us to bathe her immediately and to watch for worsening symptoms and seizures. After bathing her we did research online and came across this website. I am infuriated that a company continues to sell this product. I am saddened by the number of deaths this product has caused. Poptart is like my baby. She is a part of the family and would be devastated if anything happened to her. So now I will pull an all nighter to make sure she is ok. In the mean time sign my petition to try and get theses dangerous products removed from the stores or at least get them to change their “recipe”.

Worried for my babies

I’m worried for my little babies! Recently I found out my cats have had fleas so I went to Target to get some flea treatment.My cats don’t “love” baths so I decided getting a spray for them would be easier.When I read this page I became gravely worried for my 3 kittens and their mother.So far I have only seen one sign that I’m worried Hartz might have caused is that the mother cat has been coughing and sneezing,and I don’t know exactly why.It doesn’t seem to affect the kittens,but so far I have stopped using that spray and decided to stay to the baths that aren’t from Hartz.

Hartz Ultra Guard Plus Spray ; flea & tick :: WARNING !!

Be careful of this PRODUCT…If you use it , use sparingly and not recommended duration. I think with more time and extra bathing. I think this product caused the DEATH of my BUDDY. A long hair tabby of 11 years old who was in GREAT HEALTH. (ELVIS)..In the last few weeks his normal activity changed. He went into some hiding and eating less…This yesterday morning , he walked in like he wanted to run somewhere. He turned and fell to the rug and seizured DEAD like with a heart attack and body shutdown.I was stunned ; I tried some mouth to mouth but total no movement. It was like instant DEATH ; but this was after a few weeks. A total healthy ADULT CAT ; in a few weeks; GONE !! This product may kill the bugs ; but it KILLED my loving cat !!!


Our dog was very sick after having his a Hartz flea collar

 on, He became weak , not wanting to eat and could’nt

walk he was just out of it. this went on for 2-days.

We have a cat that after we put Hartz flea meds on him, is not shaking and not really moving too much. He has a VERY big sore on the back of his neck, where we put the medicine. PLease help. What can we do??

This website possibly saved the lives of 5 cats!

I am so thankful to have found this website when I did!

We had purchased Hartz Ultraguard Pro flea & tick drops for cats. We were going to use these drops on my cat, my aunt and grandparents 3 cats, and a family friends new kitty. I was getting ready to apply this drops onto my cat, so I googled this brand of flea drops to get directions, when this website came into the results. So I clicked and read all of the awful stories on here from this nasty product, and immediately threw it in the trash and contacted my aunt and grandparents! I had them read the stories on this website, and they were horrified and disgusted, but very thankful they had not yet put any of this POISON on our cats! It is a truly a great relief that we avoided a tragic disaster!

I am so sorry for those of you who found about this product too late, and lost their best friend(s). But I really appreciate that you all posted your stories, which saved the lives of 5 cats last night as well as saving us from broken hearts and regrets! Thank you so much! If I hadn’t found this website, my cat probably wouldn’t be cuddled up on my lap right now.


Hartz Flea and Tick Collar

I thank you all for posting on this site and for whoever created it.

I bought a new flea and tick collar for my cat, Cablo just two days ago. She is normally very vivacious and gives me kisses when I come home, has a voracious appetite and is a young, fresh, healthy girl. Today when I woke up, she wasn’t sleeping on the foot of my bed, which she does every night. She was sleeping on the couch in a ball very solemnly. I went over to pet her and there was no purring, no kisses, nothing.

When I open the fridge Cablo will run from great distances in hopes to get more food – it’s never enough! She loves to eat! But when I opened the door this morning, she didn’t move. I carried her over to the bowl and she was crying, which is very unusual. I had to go to school and was so upset all day thinking of her in distress.

Hoping she would be better when I got home, I was saddened to see she hadn’t moved from the couch, didn’t great me at the door, she hadn’t eaten a bite. I was convinced she ate a cotton bud and so worried about the possible vet bill.

After trying to figure out what may have gone wrong, I found this site and immediately took her new collar off and bathed her (which she hated), but she seemed so much happier instantly! We played a little bit, she ate a little and is now resting. If she is not back to normal by tomorrow afternoon I will take her to the vet, but fingers crossed she will be back to her jovial self in no time.

I will never buy a Hartz product again and told all of my friends the same.
