Tuna-flavored Churu type, perfect for brushing your cat's teeth. - Brand: CIAO - Product Name: Toothbrushing Churu - How to use: Apply to a toothbrush I thought I was doing proper dental care, but my cat developed periodontitis. I've been diligently brushing their teeth and using over-the-counter dental care products every day. They had six front teeth, but three have fallen out, so I bought this to prevent further tooth loss. I have several, so I'm offering one for sale. Thank you for looking.
