I was reading something about this. Are they frigging insane??! One of them suggested brushing them after every meal. My cat bites the living fuck out of me. He's only a few months old. I couldn't get near his mouth if I tried.
I'm all for teeth cleaning. I've heard bad stuff about putting some anti-tartar fluid in their water bowls. Somewhere they suggested certain toys to give them to chew on which helps take the tartar of their teeth.
My cat still has his baby teeth.
