These are little kitty treats made from freeze dried poultry which has been treated with enzymes to retard plaque formation. They contain a mild dental abrasive like toothpaste, so chewing cleans the teeth as if you were brushing them. In our experience, cats given one chew a day needed their teeth cleaned only about half as often as cats cats receiving no dental care.
In kitty focus groups, approximately 90% of the cats tested accepted CET Forte Chews eagerly. If your cat seems suspicious at first, remove the gelatin coating and moisten the treat with a few drops of water.
