BEST CAT PRODUCT EVER

I bought this for my cat who has stomatitis. I only got this because it's like a tenth of the price of the medicine I usually give him which wasn't really working much or at all so I wanted to try something else. Its only been a week but I've noticed that his breath is already so much better and he LOVES this stuff. When I started givjng this product I also stopped giving him his previous medicine and brushing his teeth daily (instead a few days or once a week) just to see how well this product works and so far everything has already improved a lot and so much more than when I was giving him expensive medicine and brushing his teeth daily for months. Everytime I put some in his water he instantly runs to it and drinks a lot of it. I expected it to cause him to not drink as much water but it's done quite the opposite. I've always had issues with trying to get him to drink water but as soon as I started using this he's been drinking at least 3x what he usually would in a day which is amazing.

price was right. my dog goes into kidney failure because of his heart medication sometimes and the best way to combat against failure is electrolytes. This has Arm %26 Hammer Baking Soda in it, which helps restore electrolytes balance. You can add 1/4 tsp. baking soda to 8 oz. of water and have a simple electrolyte drink for anyone. Including your dog. This stuff does have other ingredients I'm not comfortable doing alone so thank u Armee Hammer 😉

Definitely think it makes a difference in dog breath. I add it to their water bowl and they don't seem to mind. I'd add it after water is added to bowl if you do it first and then add water it gets foamy.
