I bought Pet Kiss for my aging cat (she's nearly 19), who has kidney disease and can't get her teeth cleaned by the vet any more. I wanted something that was completely natural - no chemicals, preservatives, dyes, flavorings, alcohol, etc. to stress her kidneys. Pet Kiss fits the bill! She's very picky, but didn't even notice when I added it to her water. The one problem I had was that, if the water in the dish sits for a couple of days, it will grow mold or bacteria (no preservatives). So I would make up a quart of water (or a gallon) in advance and store it in the fridge. Then I'd completely change her water and wash out the dish every couple of days. This solved the problem, but there are no directions to refrigerate the treated water after it's made up, or to change the water completely every day or so. My cat's teeth and gums seem to be healthy, and her breath has improved.

I'm not sure how this is working because we have at least 4 things to keep our dogs teeth clean. They are both 3 years old and have never had their teeth cleaned. When the vet looked at their teeth she said they were really good and clean. I use this in their water, use a spray on their teeth, brush once a week with a toothbrush, and use bully sticks. I really think that the bully sticks are what cleans their teeth the best. They love them and chew on them all the time. They mostly chew on the very back teeth, which builds up tartar and plaque the fastest and the bully sticks clean them completely. We hold the bully sticks while they are chewing as a safety factor for choking but if it's long enough, that probably won't happen. I am sure that this plaque and tartar control in their water also is a helping factor in clean teeth. In fact, all that we do is a factor in their clean teeth. We are so adamant about keeping their teeth clean because I have been through what happens when you don't and have lost a treasured pet because of bad teeth.

This additive is so great Elliot's vet was just amazed at how healthy his gums and teeth are.

I have a 12 year old Cavalier King Charles Spaniel with a lot of tarter on his teeth (it is very hard to brush a short muzzle dogs teeth well, when he is not fond of the process). I have been using this in his water for about 8 weeks and the reduction in the tarter is amazing, even my Vet. commented on it. He asked me what I was doing differently. I told him what I was using and he said it made it easier to clean his teeth, therefore, took less time to clean his teeth, reducing anesthesia time, (which is especially important with older dogs). The dogs don't seem to notice it's in the water and it helps keep their breath fresh. I have a 4 month old Golden Retriever, and even though she still has baby teeth, she gets it too. I figured I would start her out right. She won't have that sweet "puppy breath" forever.

I have one large bowl for the dogs and cats. I use this in every refill and the animals like it.
Many years ago my vet told me that the zinc was good for getting teeth clean and keeping them clean. He was correct.
I still get their teeth cleaned every few years, but they stay much cleaner and their gums are in great shape.
And I find that the cats drink more water when the additive is in it. Since cats are notorious for not drinking enough water, then this is another advantage to using this product.
So, I have been happy with this product. I would have no problem recommending it.
