Elite Science VET is a nutritional supplement for dogs and cats that supports 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 ordered too much with a friend overseas. I'm selling it to cats and dogs in need.
