ROYAL CANIN® Oral Care is a precisely-balanced nutritional formula that helps maintain your cat\'s oral health by reducing the formation of dental plaque. It also contains a high protein content to support and strengthen your cat\'s muscles, bones, and teeth. When looking for a diet that benefits your cat\'s teeth and oral vicinity, it\'s important to be aware that ROYAL CANIN® Oral Care performs two actions: Mechanical and Chemical. ROYAL CANIN® Oral Care is specifically designed for targeted action, the Oral Care kibble size, texture and shape encourages cats to chew thoroughly. This mechanical action produces a daily tooth brushing effect that helps reduce the formation of dental plaque on teeth. This formula is also enriched with an active dental agent (calcium chelators) which performs a chemical action by trapping the salivary calcium to help limit dental plaque mineralisation. ROYAL CANIN® Oral Care has been clinically proven to show results after just 28 days of continued use, reducing up to 59% of tartar formation.
