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.

Ear mites

Use the ear mites med for 9 days per the directions 7-10 day request. My cats ears ended up very red with scabs and soreness … upon a visit to the vet was told he had yeast infections in both ears, nothing about my cats diet or surrounds changed except for this “medicine”

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!
