I don't know, so far I thought it would only be natural not to brush an animals' teeth, especially when they eat hard food.
Now I've read several times during the past weeks that it's more and more recommended by the vets and that cats that eat can food would easily get tartar and lose their teeth. My Katz (R.I.P.) lost her teeth very young, she was only 7 when it started. So I thought I'd try to get Luna (10 months) used to it and she seems to like it, so why not?
