Julie has very white pretty teeth. She is still young, but also she eats only dry food. She wants nothing to do with canned or soft food, no people food, and no treats. I got some little crunchy kitty treats that are supposed to be good for keeping tarter under control. She won't eat them as treats but I can put the suggested 10 pieces a day in her food bowl and she will eat them with her kitty food. I suppose it is good that she is a dry food only kitty. I buy a good formula so she gets plenty of nutrients. She drinks a lot of water, makes plenty of 'kitty cakes' in her litter box, and is happy so thats good with me.
