Didn't notice a difference and I added it to the water fountain. One of my cats stopped drinking water and the other started throwing up, I realized it could be the water. Opened the tank and there was green slime everywhere. This metal fountain has never slimed before. It has to be this liquid. Gross. I wish I could get a refund

I appreciate that this product exists, but my cats will not drink their water because this liquid smells and leaves a bad taste in their water. I wouldn't drink it and they don't want to either.

Seems to help gum and tooth health

Can't be sure if it's this, or cat Greenies, or may cat would've been okay anyway, but his teeth have been in good health using a combo of this water additive and

Can't be sure if it's this, or cat Greenies, or may cat would've been okay anyway, but his teeth have been in good health using a combo of this water additive and cat Greenies. Rescued as a feral kitten, he has had about half his teeth removed, but since this additive (and Greenies), his teeth and gums are great.

Cats will drink this one

I’ve tried others and they wouldn’t drink the water. Not a problem with this add in.

Dental water additive for cats.

This water additive is really good and definitely worth the money. It helps with bad breath, and other things. At my cats last vet appointment 2 and half years ago

This water additive is really good and definitely worth the money. It helps with bad breath, and other things. At my cats last vet appointment 2 and half years ago the vet said his teeth looked really good for his age. I also give him the greenie treats which do the same, but I give him the smart bites which are the small ones.

Dental Additive

Great additive! I put one square in the water bowl every day. My girls don’t mind the taste of this and I feel like I’m doing something to help.
