Feline Greenies™ Dental Treats are formulated for cats 1 year of age or older. For a healthy dental benefit, feed a 1 lb adult cat 8 treats, two times per day in conjunction with your cat's regular diet. Adjust the amount of main meal to compensate for calories delivered by treats. Always monitor your pet while feeding treats. Provide fresh drinking water at all times and see your veterinarian regularly. To help maintain freshness, we recommend closing the lid tightly and storing in a cool, dry location.
