Caused vomiting and diarrhea and loss of appetite in both cats
23 July 2023SMM

originally posted on chewy.com

One of our cats has some dental issues, and our vet recommended a water additive. I added this to their water, and a few hours later one of our cats vomited--this was the first time he's vomited in the six months we've had him, so it was significant. The only change was the water additive, so I dumped out the water, washed the bowl and refilled it with fresh water (without the additive). Our other cat vomited shortly after, and both cats had diarrhea for three to five days. Both cats also didn't eat well for several days, refusing meals altogether at times. It was bad enough that I was almost ready to take them into the vet. It was almost a week until they were both back to normal--all from one single use of this water additive! Terrible product, do not recommend.

I have 2 dogs, one is a little older and has never let me brush his teeth, and one is a puppy. My older dog has had dental extractions and used to always have problems with his breath no matter what dental chew products we tried. OxyFresh has been absolutely game changing when it comes to their dental health. After a week of using a capful in their water bowl, their dog breath odour was completely neutralised! And both of their teeth have remained so white and clean, with my puppy even receiving compliments from the vet about how beautiful her teeth are!

This additive is effective with keeping the pet's breath fresher and teeth whiter for a longer period of time. The first pet that we introduced it to is no longer with us, but her 17-year-old teeth were still beautiful and intact when she died. Even her vet was amazed by the condition of her teeth. This high-quality, USA-made product receives "four stars" only because of the price ... it's a tad high compared to other products on the market ... BUT we will pay it, as our recent mistake of buying a different product (thinking that it was THIS) resulted in one pet vomiting and a second pet refusing to eat. Now that THIS is back in our home, the dogs have returned to having happy smiles and we are no longer worrying about their teeth. Truly, pet owners will see results ... MoreThis additive is effective with keeping the pet's breath fresher and teeth whiter for a longer period of time.

I can't say that it will completely eliminate the need for brushings and cleanings (in our case, it did), but it should greatly reduce it. I'm not "against" the competitor's product either ... it may work as well; it just didn't "agree with" our pups. In any case, I'd deem it safe to say that your pet kisses will at least smell sweeter!

I think it's working
4 September 2024

One of my cats has serious health issues. Because of that, the vet has been reluctant to put her under anesthesia. A few months ago, we were suspecting she had a bad tooth, I I agreed to the risk of having her undergo general anesthesia. It had been six years since she'd had a dental. We were all shocked that she had no cavities at all. Except for needing a good cleaning, her teeth were perfect & x-rays showed no problems at all.On her dental six years ago she had to have three extractions for resorptive lesions. I've been concerned that she may be having continued problems with these lesions since they tend to recur. I can't claim that the Oxyfresh prevented them, but I definitely believe it prevented regular cavities.

Love this product!!
7 August 2024

I started using Oxyfresh about a year ago with my cats. It is almost impossible to brush a cats teeth, so I was hoping this product would help remove and prevent tartar buildup. I use the Catit water fountains and add Oxyfresh to the water at the maximum recommended dose. This past week during the check up of two of my sibling cats, my vet commented on how clean and healthy their teeth and gums look. Both of these cats are rescues who did not get extremely good nutrition as young kittens. Lack of good nutrition during development sometimes predisposes cats to have dental problems. They are now 4 years old and both have teeth that are very white, completely free of tartar and any signs of tooth decay. Their gums are very pink and healthy with no sign of periodontal ... MoreI started using Oxyfresh about a year ago with my cats.

MADE MY CAT VERY SICK
17 July 2024

Added one cap to my cat’s water fountain and three days later I woke up to him having diarrhea and vomiting multiple times. He was extremely lethargic and could barely move. I took him to vet that day and they said it was probably this water additive- as it was the only change to his routine. $150 later they gave him a shot and sent me home with medication. He is looking slightly better day two, but it’s so sad to think it was because of something I gave him. PLEASE read these one star reviews and don’t chance this product. I can’t image what would have happened if we would have continued. Hoping this did not cause any permanent damage. CHEWY REMOVE THIS PRODUCT !!!

Seriously Helps with Bad Breath
13 August 2023

As my dog is getting older, her breath is really starting to reek. I’ve tried a lot of other solutions, but outside of spending thirty minutes trying to get her to cooperate as I brush her teeth, nothing has helped. So I decided to try this and the effect was almost immediate. Her breath smelled better the next day. I was genuinely surprised at how well it worked, even thought maybe I was just imagining it, but recently when I took my dog on a road trip, I couldn’t give her the water additive and her horrible breath came back so bad that it was impossible to drive without the windows rolled down. That experiment proved to me that it is in fact working, though it isn’t a permanent solution.

It’s not like her breath started smelling all minty fresh or anything, just like normal dog breath, so don’t expect it to do anything more than that, but if you’re able to afford it, I’d at least try it and see if it helps.

Still need to brush but works on breath
6 July 2024

Had the smaller bottle for about 3 months. Ran out and didn’t repurchase because I wasn’t sure it was working. IT WAS, haha. Can definitely tell these guys don’t have this in their water anymore. Still have to brush dog’s teeth, but this absolutely works on her breath. She shares water bowls with two cats and none of them had any tummy upset and this works great on all of their breath. Never had an issue with cloudy water and they really can’t tell it is in there, and I have two of the pickiest cats on the planet.

Terrible product - made cat extremely sick
22 July 2024

I had this out in my dogs' and cat's water dish for two days. Dogs seemed fine, but after the second day, my cat seemed SUPER off - wouldn't eat a bite of food, sitting in a dazed way, no purring (which is super unlike him) and when I tried to pick him up, he was stiff and meowed uncomfortably. It seemed like he was depressed and his body was completely shutting down.The overall reviews of this product look great, and the packaging claims to be vet-approved and non-toxic. I also trust Grove to carry safe products. After my cat's adverse reactions, I went to look at the one-star reviews - many of the reviews explained the same negative side effects. Sodium hydroxide, one of the ingredients, is Lye which causes chemical burns. I immediately changed out the water ... MoreI had this out in my dogs' and cat's water dish for two days.

Sodium hydroxide, one of the ingredients, is Lye which causes chemical burns. I immediately changed out the water dish water to plain tap water. I wanted to avoid bringing him in for fluids (vet bills = $$$), so I took off of work and gave him tap water through a syringe multiple times throughout that first afternoon.He seemed slightly better by the evening - I was able to get him to eat half a slice of American cheese. But he was acting odd still (eyes looked cloudy and he wasn't able to find the cheese if it dropped onto the floor). Did some eyes tests and it seemed like his vision hadn't gone completely. By the following morning, I got some purrs out of him so he was improving. Syringe fed him tap water a few times throughout that day. By the end of the second day, I had him back to normal.I WOULD DEFINITELY NOT RECOMMEND THIS PRODUCT. It clearly has some bad ingredients that can cause real harm to some cats. I thought we'd lose our dear cat forever, and I'd have to live with the guilt of being the one that basically poisoned him.

Works to clean teeth but at what cost
9 January 2023

We have 3 cats and wanted an easy way to clean their teeth, they all took to it well and the vet was very impressed with how clean their teeth were. Note: their food is vet approved and been on the same diet for 7 years without issue. We also confirmed we were measuring the correct amount of water to additive. Unfortunately after 6 months of sustained use of this product, we noticed our female began having trouble urinating and would squeeze only a few drops and with blood. She’s never had any health problems before. Vet confirmed urine contained crystals which formed in the bladder caused by the minerals in the additive (we took the bottle). If we kept using, those crystals would clump together and require surgery for removal.

I will also note that our two other cats never experienced any problems with it. Yes it cleans their teeth, no it won’t work for everyone. Use at your own risk.
