Hill's Prescription Diet t/d Dry Cat Food is clinically proven to reduce plaque, stain & tartar build-up and clean up to the gum line. The kibble contains an exclusive matrix of fibres which act like a toothbrush to scrub the tooth to remove bacteria. The large kibble size, shape and texture cleans the teeth to the gum line to promote healthy gums and teeth. Exclusive feeding of Hill's Prescription Diet t/d Cat Dry Food has been shown to be more effective than tooth brushing, due to the fact that only a few cat owners brush their cats' teeth regularly.
