I had never given any thought to kitty teeth. The vet has never mentioned it and even my geriatrics did not have problems as far as I know although they did have some bad breath which probably WAS bad teeth. So, I am also thinking that it would be a good preventative measure to start caring for their teeth. I saw special toothbrushes at Petsmart - but really, think baby toothbrushes would be fine.
Funny thought - they make yummy poultry toothpaste for kitties - why not chocolate toothpaste for us??
