Chew your way to a healthy heart! Treatbrush Oral Care for Cats was scientifically designed to make cat oral care, easy, stimulating and fun. Your cat brushes his own teeth all the way to the gum line, as your cat’s teeth penetrate the patented “Floss Slots”. Insert your cat’s favorite treat and turn any treat into a toothbrush. Our unique mylar cross stitch gently scrapes the plaque and tartar off the teeth, and the course sponge interior grabs the debris and keeps it away from the gums. Machine washable.
