Be sure to get pet toothpaste -- don't brush your cat's teeth with human toothpaste. Human toothpaste contains flouride, which is a poison. It's fine for humans because we generally spit out the toothpaste, but cats will swallow it. So due to ingesting the toothpaste, plus their much smaller body mass, the small amount of flouride in human toothpaste can be toxic. Look for pet toothpaste with enzyme action and without
flouride. I use CET brushes & toothpaste myself and they've worked very well for me and my cats. Nice teeth, nice breath.
