I understand that there is a liquid product which is available that you put in a cats drinking water that is supposed to oxygenate and has some sort of enzymes that is supposed to help prevent teeth and gum problems in cats. Have you heard of it? And if so, do you know if it is of any value?
I do not know of anything that you put in the water but I do know cat treats are available through C.E.T. I am not sure if our site sells these treats but your vet might. Good luck, vetcare
