This is a periodontal care product that can be used for both dogs and cats! It's a product that only needs to be licked once a day! You can also use it with a toothbrush! The film has been removed, so it's listed as "like new," but the product itself has not been used, so please use it with confidence! I bought too much, so I'm giving it away to someone who can use it! The expiration date is July 2026! It will be sold as a set with Plaque Care Sheets!
