Let's get back to the brushing of cat's teeth for a moment. No, I have never tried to brush either Simon nor Kelly's teeth and I don't think I will. Simon might be very brave at the vet and will not complain but Kelly ... well, this is a different story. What I was told to do is give them chicken-necks to chew on. It's not bones but gristle and will not harm them. I for some reason don't like to give them chicken bones with all the stories I heard about it. If I am not sure, I will not feed. And yes, Kirsten, I also give them Whiskas Dentabits. I still have to make sure Kelly will chew it and not just swallow.
