Elite Science VET nutritional supplement for dogs and cats, supporting gums, gingiva, and joints. 1-TDC® contains a unique blend of the beneficial ingredient 1-Tetradecanol Complex. This helps to maintain and support healthy gum and gingival function. 120 tablets, unopened. It works wonders for my cat with stomatitis, but I overbought it when I asked a friend overseas to get it for me. I'm selling it to any cats or dogs in need.
