Our cat Mimi, within a week looks to be healed. We are attentive animal parents, none -the -less we discovered a hole/indentation on the outside of her mouth the size of a pencil eraser. Immediately plastered it with live clay which she did not mind and started dosing 500ppm silver, while researching, finding and ordering this miracle product. I also looked inside her mouth and found gums looking a bit pale along with some lines of red along the back teeth with heavy tarter . While waiting for delivery of Healthy Gums , I would smear live clay along her gum line daily. Always keep silver and clay separate from each other. In our case, I gave it about 30 minutes apart. Her condition stabilized. Then having received the product, an application, 3 drops twice daily applied with a Q-tip along her gum lines. Within a week, the live clay healed the outside so we can not even tell where the original site of the hole was. And in her mouth, all the gums are healthy with no indication of red lines or tarter(it all disappeared) . Just wow! In gratitude for Pet Wellbeing Healthy Gums for Cats, and whoever formulated this. Thank you.
