Hartz Ultraguard

My wife bought Hartz Ultraguard at Walmart and applied it to our one year old cat. Five minutes after application, our cat began running around the house panicking and meowing very loudly. She began hiding and after I found her, she was panting as if she could not catch her breath. Additionally, one of her eyes appeared to be swollen. We called an emergency vet’s office and told them what we had used, and she told us to immediately wash it off her fur with Dawn dish detergent. She said this stuff is poisonous to cats and she’s seen multiple cats die as a result of having this applied. Just a warning to all: DO NOT USE THIS PRODUCT. It can kill your cat! If you’re reading this because you made the mistake of buying and applying it, wash it off your cat with dish detergent as soon as you can!


Please please do not feed anything from Hartz to your pets. Two of our three dogs ate these oinker pig wrap chews. Both are suffering from severe diarrhea going on three days. We are going to the vet tomorrow to determine how much poison is in their system. We just had to put down our 17 year old lab. If I lose my terrier mix or my boxer mix due to this crap made in China, Walmart and Hartz will be sued.

Skin reaction o

Ok so I have 2 cats and I just medicated them a few days ago and I say on one of my kitties a small bald spot where the medication was aplied and then I looked a little closer and saw about an inch and a half in diameter scabbing and red spots and after reading up on hertz products I’m starting to worry, I just rinsed out her fur for about 10 mind and decided to give her a bath. She has been acting completely normal aside from what looks almost like chemical burns. Do u think she is in the clear? Is she going to be ok? Should I worry or am I over reacting? I have used hurts on her before and she has never had a reaction like this before.

“Extra Gentle” Hairball Control

I had two cats named Roxy and Jerri who I gave baths to on Thursday. Roxy was fine after her bath but Jerri just kind of laid there after. I gave them both a treat so they’d feel better and was gone for a couple of days. When I came back, Jerri seemed to have some diarrhea so I cleaned it off of her. She didn’t move much when I did and she just laid around for the rest of the evening. This morning, she was laying down and I picked her up. She meowed and I put her down, like I’ve done many times before. She took a couple steps, laid down and started moving weird. She seemed to be having trouble breathing and I didn’t know what to do. I considered trying to give her CPR but when I went to lift her head up, her pupils were dilated and I knew that it was too late.

Hartz Ultraguard

A couple days, I had gone to Walmart to pick up flea medicine for my cats. I grabbed Hartz Ultraguard Fleas and Ticks drops, and didn’t think much of it. The next day, I applied the drops on my two cats, 4 and 7 years old, both definitely over 5 lbs like the packaging says, in between their shoulder blades where they can’t lick at it. They winced at first and ran off, I figured it was just the smell and the feeling of the ointment setting in. About 30 minutes later, I noticed my younger male panting and running around in a panic, shaking. I called the closest vet clinic and explained everything to her. She asked what brand, I told her, and she replied, “I thought you were gonna say that. You need to get him to Med Vet (emergency vet) immediately, that brand is extremely toxic for cats.” I called three different people looking for a ride while I shoved my panicking cat into a carrier (he has extreme anxiety issues already for unknown reasons) and I chased my other cat and kept them both in my room. My aunt picked up the phone and I explained to her what was going on and she called the vet as she was on her way. She texted me directions of what to do – wash the site with cool water. So I got both of my cats in the bathroom, and I practically threw my cats in the sink (one at a time). My dad had to hold my older cat while I scrubbed vigorously at the back of her neck with Dawn dish soap – she HATES water, and won’t let anyone even hold her near the sink, so it was a difficult time. My dad took her in a towel and then I got my younger boy in and scrubbed him up. By the time my aunt got to my house, she was still on the phone with the vet. We decided to keep an eye on them before bringing them to the clinic, and as of now, they’re doing fine. I have never had this happen before with different brands, and this was a scary situation I didn’t think I’d have to go through while trying to protect my cats from fleas and ticks. If someone happens to use this brand, wash the drop site IMMEDIATELY with pet soap or Dawn dish soap. I noticed it also had a bit of a film, so I made sure to scrub my cats skin with my nails to get it all out – my sink was covered with fur afterwards. By the time the whole situation began to settle down, I noticed my room reeked of chemical from struggling with my cats early. This brand is terrible, and now I’m going to be sure to read reviews on ANY pet product before buying/using it!

Hartz UltraGuard topical flea and tick prevention for cats and kittens

I gave both of my 2 year old cats Hartz UltraGuard topical on Tuesday and my female is fine but my male is in bad shape. Wednesday he was very lethargic and was not eating or drinking. Thursday I looked up reactions to this stuff and was horrified at what I saw. I gave him a bath and have been giving him water with a dropper but he has not used the bathroom and is getting worse. He has an appt today(Friday) at 10:30 and I just hope everything is ok but it’s not looking great. This is devastating to watch.

Cat freaked out after applying flea and tick drops.

I applied the Hartz flea and ticks drops for cats and kittens on my 1 year old cat Clementine. As soon as I put the drops her skin turned red and she started panting extremely quickly. She immediately ran under my bed, I got her out of there to wash it off with dawn soap and water. She was still breathing heavily for about 6 more hours and then she threw up. She is thankfully fine now but I consider myself lucky.

Flea Collar Horror Story

I am the proudest of cat mothers to my two kittens. They’re 8 and 10 months old respectively, perfect little tuxedo kitties. About a week ago we got the younger one a flea collar because he had started to give some of the rugs fleas.
I’m not the adult of the house, so i asked my mom to buy him a flea collar. She came back with the Hartz reflective flea and tick collar. I looked at the packaging and saw the label ‘This product contains chemicals known to the state of California to cause cancer’. My poor kitten was absolutely eaten up so i figured it would do for the next few days/next week until i could go get them one myself.
Not even a week later my cat is throwing up and losing control of his bladder. First he urinated on the bed (which he hasn’t done since he was a TINY kitten), and i just got woken up to the sweet sound of my cat throwing up in about 3 different rooms.
I googled it and sure enough, the collar he had on (which id removed a few hours before he threw up) was from a brand known to kill cats.
I chose to share this story because if i didn’t know about the side effects of some collars, i would’ve kept it on him. We aren’t well off enough to be able to visit a vet regularly, and he probably would’ve have died.
Please do not use Hartz collars on your animals. I’d hate for anyone to go through an unnecessary death.

Ultraguard Pro

The other day I stopped at Wal-Mart to pick up some flea medication for my cat. I had applied the flea ointment to the base of her skull on the back of her neck as directed. I had used this product before with no issues. Bayou had fallen asleep like normal that day. The following day I’m getting ready for work and she leaves my bedroom and lies down in the living room. After I get home from work she’s in the same spot and it concerned me. So I picked her up and she protested like she was in pain. I washed her with dawn dish soap to get the ointment off of her. She didn’t provide a lot of struggle Which she usually does when getting a bath. She’s been extremely lethargic. She’s not eating or drinking anything. I’ve been using a rubber syringe to make her drink some water but she still won’t eat. It’s been 2days now since she’s take the medication and I plan to take her to the vet in the morning since there isn’t an available veterinarian at this hour of the day. I’m never using this poison again. I hope she is alright.
