10 years + and no more problems
Two of my cats (mother and son) were experiencing gum problems and were quite poorly due to fact they were not eating properly. The vet told me it was a hereditary problem with them both - he tried all sorts, then eventually under anesthetic a good clean and removal of tartar build-up. At that time Hills had just brought out the Oral Care Kibbles, so he suggested I give them a go. Miraculous, just used to give it with wet food to these two cats, but my other two love it as well, so they all have it now. No mouth problems since in the ten years or so been using it, and all have clean white teeth! Best value is 5Kg bags.
