Review on Dental Fresh Water Additive for Cats - Original Formula 8 oz: Effective Bad Breath Treatment & Teeth Whitening, Enhances Oral Health by Beth Martin

Impaired breathing but seemed to cause strange behavioral changes over time which disappeared when the product was removed. She's 20 and thought maybe that's her age. She had an appetite for the product, constantly pestered her to be fed, but tried everything that could be indulged. She ate out of desperation, but lost weight and was already slim. They have to close at night if you want to sleep. No longer loves and is not playful. She took the supplement out of the water and now eats when fed, showing her former character. The product was great for her breath. The price is good. Easy to use. We just couldn't help it. Maybe 20 years is too long. I would suggest you give it a try and if you notice a drastic change in behavior and take it away you probably need to try something else. It doesn't seem to have done any permanent damage to my cat. She is the former. Just observe the behavior of your pets.
