Ideally we should brush every day. If you can do less frequently still better than no brushing.My goal is to get Salem on a brushing schedule. How often do you think a cat should have their teeth brushed? I am thinking maybe twice a week to start out. I don't think I am going to give Salem the chicken necks right now (maybe never) due to the risks @Azazel mentioned. But, I might give her bits of meat. I had always planned to give her the raw in conjunction with the brushing not instead of. I actually have a malt flavored enzyme cat toothpaste that Salem tolerates fairly well.
