Brushing my cat's teeth

Daily brushing is most beneficial and will help to establish a routine. Brushing a minimum of 3 times a week is helpful if your schedule cannot accommodate daily brushing. "It is best to teach your cat to accept brushing while she is still a kitten."
It's never too late to start brushing your cat's teeth – even senior cats.
However – it's critically important to take your cat to the vet first so that your vet can tell you if your cat already has dental disease.
There are various ways you can do some cat teeth cleaning at home naturally and without the effort of brushing. These include changing their diet or food intake, using tools of natural dental care for cats such as gels, water additives, and dental chews or toys, or simply giving them a bone to chew on.
You can also use a finger toothbrush, gauze wrapped around a finger, or continue using a cotton swab. Check with your veterinarian if you are uncertain of which brush to use. Ultimately, it is preferable to use a brush where the bristles can reach just below the gumline at the tooth/gum interface.
Bacteria buildup: Odor-producing bacteria that grow on your cat's teeth and gums are the most likely culprits of bad breath. An over-abundance of bacteria can occur if you fail to clean your pet's teeth, allowing tartar and plaque to build up.
