Please do not use this product on your cats or dogs! It contains xylitol which is toxic to both cats and dogs! Even in small quantity's it is toxic, it amazes me that they would put out a product like this with xylitol in it! Makes it hard as a pet owner, please read labels and educate yourself as to what things are toxic to our animals because the manufacturers don't care.

I have been very satisfied with this product. It has consistently decreased any build-up of tartar on the teeth. I only brush the teeth once a week, so this has been a big help in keeping the gums and teeth healthy.
